West Ham United boss Slaven Bilic was delighted with Sam Byram's debut for their draw with Manchester City.
Bilic wrote in the London Evening Standard: "How quickly things can change in football. A week ago we signed Sam Byram and were thinking he could ease his way in slowly.
"Then suddenly James Tomkins is injured and can't play against Manchester City, Carl Jenkinson picks up a bad knee injury early in the match — and Sam is on!
"It was a very mature debut considering everything, especially the opposition.
"Imagine coming on and being up against Kevin de Bruyne, or David Silva — and then Raheem Sterling in the second half! He wasn't scared, though. He relished the opportunity and what helped him was that he was match fit."
