Chelsea boss Mauricio Pochettino admits concern around Carney Chukwuemeka after defeat at West Ham.

Chukwuemeka struck in the 3-1 defeat across London on Sunday.

Pochettino later said: "We need to assess him tomorrow.

"There will be an assessment tomorrow with the doctor. We hope it's not a big issue, but we need to wait."

The manager also said: "We changed Carney for (Mykhaylo) 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."
