West Ham boss Slaven Bilic could be left counting the cost of their dramatic 2-1 extra time FA Cup replay win over Liverpool after a number of players picked up injuries.

Winston Reid and Joey O'Brien pulled up injured, Cheikhou Kouyate suffered a blow to the head, while Enner Valencia may have joined them on the sidelines had Bilic not already made all three substitutions.

Michail Antonio and Andy Carroll also appeared to pick up knocks and with James Tomkins, Manuel Lanzini and Diafra Sakho already out, Bilic could be thin on numbers for Saturday's Premier League trip to Norwich.

"Unfortunately we had to pay the price with a few of them and we can only hope they won't be out for long," said Bilic.

"Cheikhou felt a little uncoordinated but hopefully he will be okay. Enner looks like a bruise.

"Joey hadn't played for long time so we hope it's just tightness, but with Reid it doesn't look good to me."
