Kilmarnock 1 Celtic 0 LIVE score as Yang and Turnbull thrown on by Brendan Rodgers

Not far off a second Killie goal.

A deep ball is floated in by Matty Kennedy that evades Armstrong.

As the winger loops back round and onto the pitch, he barges into Joe Hart and the two share a few choice words.

Killie’s tails are up, that’s for sure.

Can Celtic muster a comeback?

A powerful driving strike from Kyle Magennis forces Joe Hart into a save.

Nothing happening from the resulting corner though as the second ball is won by Hart with a high punch away.

It’s turning into a nicely poised cup tie.

Danny Armstrong then catches Greg Taylor late and the former Killie player needs a bit of medical attention.

Nothing too serious medical-wise though, just a patch-up job it appears.

Matt O’Riley delivers a free-kick from the left-hand side but it’s easily cleared by Killie.

Neither side has quite produced a decent set piece as of yet.

A Celtic corner is sent in by O’Riley just after that and it’s a better delivery but Corrie Ndaba climbs to head it away.

Abada flashes a ball across the box as Celtic click into gear.

It’s turned out for a corner at the back post but the visitors can’t conjure up a chance from it before Callum McGregor is booked as he fouls Danny Armstrong, who was off on the counterattack.

Liel Abada threatens on the edge of the area and young David Watson steps in to break up the danger.

Moments prior to that, Kyogo had a sweeping shot blocked in the box.

Right, we’re off for the second 45.

Same tempo, same end-to-end football, just give us some more goalmouth action!

Gustaf Lagerbielke has ‘defended quite well’ reckons Neil Lennon at half-time on Viaplay.

“In terms of his defending and physicality, I think he’s done fine,” he adds.

Despite a nervy opening touch that he passed out for a corner, he’s looked a solid addition so far.

Lennon also reckons Derek McInnes will be ‘delighted’ with his side’s first-half display.

A fairly entertaining first half ends goalless.

Corrie Ndaba had the best chances for Killie while Kyogo had a powerful shot saved at the other end.

Celtic have enjoyed far more of the ball, as is to be expected, but Killie have been resolute in their shape so far.

Someone has to go through this afternoon…

One minute is added on as Killie win a free-kick in Celtic’s half.

Kennedy lifts it in but Celtic deal with it.

David Watson nudged it to Stuart Findlay who whips in the second ball and Corrie Ndaba nods a header narrowly wide.

Almost 1-0 Killie on the strike of half-time.

Corrie Ndaba concedes a corner kick, Celtic’s second of the afternoon.

It’s cleared by the man who gave it away with a powerful header.

As the ball is recycled in, Killie are awarded a freekick for a foul by Holm on Watkins.

41 minutes now gone.

Gustaf Lagerbielke gives away a free kick about 30 yards from goal down on the host’s right-hand side.

Kennedy whips it into a fairly dangerous area but Joe Hart is alert and smothers the ball early.

No options for a quick break when the Celtic keeper gets back to his feet, however.

Again, this game’s hit a lull after a flurry of action.

Killie look fairly solid and probably quite content to let Celtic have the ball.

Roughly 31% for Killie, 69% for the visitors.

Yet to see any clear-cut chances for Rodgers’ side though.

Matty Kennedy drives past Anthony Ralston and checks back onto his right foot, drives inside, and draws a foul from Liel Abada.

Killie don’t do anything with the resulting free-kick though.

Moments later, Kyogo pinches the ball and flies forward but his shot from a tight angle is well saved by Will Dennis.

Smart play from the Celtic forward.

Danny Armstrong gets to the byline after some positive play and manages to dig out a low cross.

It is collected by Joe Hart after Kyle Magennis throws a leg at it but fails to connect.

Decent bit of possession for Killie in the final third.

Watson launches in a long throw that is knocked clear but only as far as Kyle Magennis on the edge of the area who has acres of space.

He opts for a first-time strike but it sails way over the crossbar.

After an end-to-end opening 15 minutes, the game’s hit a bit of a lull.

Celtic knocking it about with relative ease.

Kyogo dinks an effort towards goal that Dennis catches unopposed.

Liel Abada fires a cross into the middle of the box on the spin but there are no takers.

It was just a yard too many behind Kyogo in the box.

Celtic’s attacks are being kicked up a gear in a flash when they reach the edge of the box, it’s some seriously pacey play.

Well…

Armstrong dinks a ball forward and Marley Watkins gathers in the box.

He tries to check back inside on his left foot and hits the deck under a bit of pressure.

However, play was waved on and the VAR check was swiftly concluded in the background with nothing given.

The correct decision in the end..

Danny Armstrong drives in off of the right-hand side in his trademark style before hitting a side-footed shot at goal.

Much like O’Riley’s effort at the other end though, there’s nothing behind it and Joe Hart gathers comfortably.

Celtic burst through the middle of Killie and Kyogo touches it to Matt O’Riley on the edge of the area.

His shot at the Killie goal is far too tame though and Will Dennis holds it with ease.

Two balls round the corner have cut Killie open now.

Kyogo slides in at the back post and almost nudges his side ahead.

The low, driven ball was just a tad out of reach for him.

So, so close to an opener.

An early Celtic corner is conceded as new boy Lagerbielke misplaces a pass to Joe Hart and it runs out for a Killie ball.

Corrie Ndaba gets a glancing touch on it but it flies over the bar, not a million miles away though.

Stephen Welsh’s ligament injury that he picked up in training is now more serious than first thought.

Speaking to the media in his pre-match formalities, Brendan Rodgers confirmed he would be out for ‘three to four months’.

The injury occurred on the same day he penned a new four-year deal with the Parkhead club.

A tough blow for the player and the club.

As aforementioned, Gustaf Lagerbielke makes his debut today due to Welsh’s absence.

Neil Lennon, a pundit for Viaplay this afternoon, reckons Matt O’Riley will be wanting to stamp his authority on this Celtic team and make him a first-string choice under the returning boss.

David Turnbull started the season well and was flying but is now on the bench again amid a slight reshuffle with Odin Holm starting.

Let’s not forget, Reo Hatate is still to come back into this side too.

It’s a well-assembled midfield no matter who slots in with the ever-present McGregor.

The Kilmarnock manager tells BBC Scotland:

We take confidence from our home form, players have confidence from that too.

Having beaten Rangers here already this season and having to do so much right in the game, there’s similarities in what we need to do today.

We need to make sure we are ready and switched on.

Hopefully we can cause them problems too and try and win a cup tie.

There are similar things required to beat Rangers that apply today to try and win a cup tie.

Kilmarnock boss Derek McInnes admits Willie Collum’s call to turn down a Viaplay Cup semi-final penalty against Celtic still stings.

The 51-year-old was left incensed back in January when both Collum and his VAR official Greg Aitken turned down Joe Wright’s appeals for a spot kick when Giorgos Giakoumakis bundled the defender to the deck in the dying minutes with Celtic 1-0 ahead. And McInnes’ ire only increased when the Greek striker netted moments later to tee up the Treble winners for the first shot at their domestic clean sweep. McInnes joked, perhaps, it’s time to move on seven months later but admits the no call, on a night Kilmarnock gave Ange Postecoglou’s dominant side plenty to think about, still irks him.

Celtic boss Brendan Rodgers believes Derek McInnes can still be a future Rangers manager.

The current Kilmarnock gaffer famously turned the Ibrox job down in December 2017 to stay at Aberdeen. McInnes was out of the game for 10 months when he eventually left Pittodrie before taking over at Killie. He led the club back to the Premiership two seasons ago and this term, McInnes has already beaten Rangers on the opening day.

Celtic manager Brendan Rodgers tells BBC Scotland:

“It’s never easy here despite the scoreline might look it sometimes.

“You always have to work hard.

“You see how Derek’s team has started against Rangers and at Hearts.

“We’ll need to be defensively good but also show our quality on the ball.

“No qualms [about starting Lagerbielke], he’s been playing so he’s up to speed physically and in a good place.

“We’ve lost Stephen so ideally maybe wouldn’t have played him but he’s ready and now Stephen is out three to four months.

“This is a great introduction for him, though.

“[Holm has] been great in training and the appearances he’s had.

“He’s used to playing on these types of surfaces too.

“He’s a player who has good a big future at the club so it’s a chance for us to see him under pressure.”

Derek McInnes names an unchanged starting XI to the side that drew 0-0 away to Hearts last weekend.

It’s the third successive outing for this line up, with the same eleven starting against Rangers too in the league.

Will there be another Old Firm upset today for McInnes?

Gustaf Lagerbielke has been handed a quickfire start by Brendan Rodgers as Celtic’s defensive woes are softened.

Despite a few notable injuries to defenders, their new recruit is in form the start in the same week he signed.

Odin Thiago Holm is also handed a start.

Despite contract talks set to commence with Hatate, he is absent from the matchday squad.

Killie and Celtic met at Hampden in the semi-final of this competition last season.

Daizen Maeda scored the opener before Giorgos Giakoumakis sealed the tie deep into injury time.

Derek McInnes’ side felt they should have had a penalty, with the manager saying midweek that they ‘felt really aggrieved not being able to take it to extra time.’

Will they go one better today?

A home win ensures a different name would be on the trophy come the competition’s conclusion.

Don’t forget that the draw for the quarter finals takes place following this match and Record Sport will be running a live blog as we deiscover the last eight ties.

Bobby Williamson and Kenny Shiels have gone down in history as trophy-winning Kilmarnock managers and Derek McInnes feels they can do it again.

If we can win this one you’re one game away from Hampden so we have got to try see the bigger picture. We always try to impart to the players that there’s an opportunity to leave some sort of legacy at your club by getting to a final and being 90 minutes away from lifting silverware. I certainly feel we can win a trophy here at Kilmarnock.

We didn’t offer up anything in the two (league) games against Celtic here [last season] and it is important to show, as we did against Rangers, that there is a different side to us this season.

Obviously the draw is tough, we are up against a team who have dominated cup competitions in the last wee while so it is important for us to see the opportunity that is there. If we can win this one it can set us up nicely for the rest of the competition.

Derek McInnes appeared so close to becoming Rangers manager but turned them down when he was Aberdeen boss six years ago. The 52-year-old was part of the historic nine-in-a-row Ibrox squad and Celtic boss Brendan Rodgers beleives he could still lead his old club in the future.

I like Derek a lot. He’s a good football man who is honest and wants to develop players. There’s no doubt that he’s good enough to manage a top club again. He’s good with players and he knows what he wants.

He was very close to getting the Rangers job a few years ago and why couldn’t he manage Rangers? He’s a former player there, a very good player, who was part of a successful era for the club.

So there’s no doubt that could be one for him in the future. Because he’s an outstanding manager. Sometimes you’re under-valued when you’re a British coach, especially if you’re home-grown. But if you look at somebody’s body of work over time, you can see what they are.

“And you can see that with Derek. His teams are always up there with the best organised in the country – and really competitive. To have that, you must have a way about you with players, especially when you’re able to do it consistently. Derek has shown all of those qualities.

He is a top class manager and his abilities are Scottish Premiership level at the very least.
