Chelsea managed to get a 2-1 victory over West Ham at Stamford Bridge on Saturday afternoon.

The Hammers had a late goal ruled out much to Chelsea’s advantage.

Chelsea have been suffering this season from set-pieces, and the team’s weakness in defending set-pieces was evident yet again against West Ham.

According to Tuchel, it’s disappointing to see his side struggle to score from corner kicks but tend to concede from set-pieces when defending.

Tuchel said: “It’s strange, we invest a lot of time in it and there are not a lot of changes going on. In contrary, we are even investing a bit more in details and set-up and time.

“Maybe it is just a faze. Maybe it’s also down to talent. With Wesley Fofana we have somebody who can help us a lot.

“We did not have Kai today on the pitch who is normally one of the best for first contact. We took that kind of risk because we wanted to have small strikers on the pitch today.

“We struggle to convert our set-pieces into chances. We struggle with the delivery and with the repetitive quality in set-pieces and conceded again from a set-piece. But we are on it.”
