Chelsea manager Mauricio Pochettino has reflected on their 3-1 defeat at West Ham on Sunday.
The Blues are yet to record a win under Pochettino after being held to a 1-1 draw by Liverpool.
At the London Stadium, Nayef Aguerd headed the hosts in front before Carney Chukwuemeka fired in an equaliser.
Enzo Fernandes then missed from the spot in the final moments of the first half.
Michail Antonio put West Ham in front with a powerful strike, while Lucas Paqueta put the game beyond reach with a late penalty.
“We changed Carney for Mudryk, but we started the second half late, and then we conceded the second goal. That helped West Ham to really believe in the result.
“For us, we rushed situations. We need to be patient and open better the pitch. But when we see the data, in the last third, we had 50 entrances, which is amazing. But we weren’t clinical enough to score, for different reasons,” Pochettino told the club’s official website.
