Those in any doubt about how a large transfer fee guarantees nothing need only look here at the bleak figure of Chelsea’s Ukrainian replacement Mykhailo Mudryk. Signed for £88m last January, the winger has made seven Premier League starts so far and has scored zero goals. As a half-time substitute, he was miserable and, in some ways, the confused and wobbly embodiment of Chelsea’s confused and wobbly transfer policy.

A lot more Chelsea money has been spent since that big transfer and in Mauricio Pochettino Mudryk is playing for his third manager in eight months.

And so until the last jewel of Chelsea, Moises Caicedo. Signed last week for £115m, the former Brighton midfielder was not introduced until the hour, by which time his new team-mates were after him for the second time. There was plenty of time for the 21-year-old to make his mark, especially when West Ham were reduced to ten men after Nayef Aguerd was sent off.

But Caicedo in the center looked almost as lost as Mudryk on the left and as West Ham advanced in injury time, the Ecuadorian who has been so fussed about pounced on home defender Emerson to concede a penalty past Lucas Paquetá. to seal the game.

There was plenty of talk about Paquetá himself ahead of this game after it emerged that the Brazilian is under investigation by the FA for suspicious betting patterns.

But ultimately this was not the story of Paquetá and not even West Ham, which feels a bit unfair to manager David Moyes. His preseason has not been easy. Having lost Declan Rice to Arsenal, his own great signing, James Ward-Prowse, was impressive in patches. Later another newcomer also entered, Edson Alvarez. It still looks like there will be tough times ahead for Moyes and his team, but that only makes a day like this all the more enjoyable.

Certainly West Ham were brave and committed. However, they were also outplayed by Chelsea for long periods of the first hour, and when Pochettino and his players look in the mirror for the reasons for this defeat, it will be his own failings that will look back.

Chelsea’s new manager will take time. The latest rebuilding work on Fulham Road is starting from scratch. Pochettino probably won’t even be that disappointed by the way his team has played against Liverpool and now against West Ham. However, his team only has one point and it is this stat that will follow them into their next game. Whether or not the nature of opposition Luton Town turns out to be a good thing will depend largely on the outcome.

Here they were behind West Ham early only to equalize and then miss a penalty before half time. The villain in that piece was Enzo Fernandes and it cost over £100 million last January. So it goes.

At first, yes, and a goal from West Ham. The home side’s first corner had been taken by their new signing James Ward-Prowse in the fifth minute and nearly led to a goal when Kurt Zouma headed down and Jarrod Bowen was parried by goalkeeper Robert Sánchez.

The next delivery two minutes later was similar, curling from the right to the far post. This time, having pushed Conor Gallagher out of the way, West Ham defender Aguerd was able to head down and inside. In replays, Aguerd’s push on Gallagher looked illegal, but the Chelsea player should have been stronger too. Aguerd’s physical approach to the game was going to cost him later.

Chelsea were slow at this stage but soon recovered. Raheem Sterling has been fantastic this season and was a nuisance here. Also Fernandes with his passes and striker Nicolás Jackson with his runs.

Jackson headed home in the 14th minute before Gallagher’s shot was saved by Areola. Then, in the 29th minute, Chelsea equalised.

First, Jackson caused West Ham problems by foraying down the left side and with the ball only half-cleared, Chukwuemeka created a chance and, as a result, a goal for himself. His first touch to control a punt was good and the trick he played on Tomas Soucek to send him the wrong way was fantastic. Having cleared space for himself, the 19-year-old blasted a right-footed shot off Areola with speed into the far corner.

It was a beautiful Chelsea goal and one that heralded them, at the time, as the dominant force. They might well have won had Fernández converted the penalty awarded for Tomas Soucek’s stumble on Sterling in the 41st minute. But Areola saved his right and as West Ham emerged for the second half with greater energy, they broke through their opponents to retake the lead. advantage.

Michail Antonio has his critics and can disappear in games. But he can also make great contributions. Here his shot, low to the keeper from 20 yards, came true when he picked up Bowen’s pass down the right side. But the way he rocked Levi Colwill to take possession will have infuriated Pochettino, as will the way Axel Disasi lost the ball in midfield in the first place.

Subsequently, Aguerd’s dismissal for a second booking should have invited Chelsea back to the table. There were still 30 minutes left. But when Mudryk managed to throw a very good chance across the pitch to the teammate who had provided it, the bewildered Sterling, it was apparent that Chelsea’s run was over. By then, Sterling was out of the game.
