West Ham boss David Moyes praised Said Benrahma's impact for victory over Fulham.
The winger set up Tomas Soucek for the winner in injury-time.
Moyes said, "Said Benrahma has made an impact off the substitutes' bench and we want him to make an impact, but we've had players making an impact every week like Pablo Fornals and Jarrod Bowen, so we've got good competition.
"We want Said to come in and help us and he did tonight – well, he didn't in the last minute but I wouldn't put it all down to him because we've got to defend all the four minutes after we scored our goal better.
"We got away with it, and we won't always get away with it, but it's something we need to learn from.
"Said set Tomas Soucek up brilliantly and Tomas will get goals, there is no doubt about that.
"One of the problems tonight was our crossing quality was really poor and we didn't deliver good enough quality into the box when we were in positions to do so.
"We had Tomas in the box and Seb Haller too, and we were hoping to get something aerial for him to score from, but I felt our crossing quality was really poor."
