The 19-year-old started at the London Stadium and brought us level in the 28th minute with an excellently taken goal; Chukwuemeka shifted the ball beyond Tomas Soucek in the penalty box and whipped a shot into the far corner.

It was a strike worthy of Chukwuemeka's first-half performance. Unfortunately, just before the interval, he dropped to the turf, held his knee, and needed to be replaced. That the midfielder was unable to leave the pitch unaided was cause for concern.

'We need to assess him tomorrow,' said Pochettino after our disappointing 3-1 defeat. ‘There will be an assessment tomorrow with the doctor. We hope it's not a big issue, but we need to wait.'

Mykhailo Mudryk was introduced for Chukwuemeka at the break and Pochettino tweaked his side's set-up. It wasn't a decision that paid off despite the fact we controlled much of the second period.

'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.'
