West Ham boss David Moyes admits he wants strengthen his attack in January.
Said Benrahma will miss most of January on Africa Cup of Nations duty to increase the pressure on the London club's limited options going forward.
Moyes said: “Maybe we can add to the front line in some way possible which might give us other alternatives as well.
“Said can play a couple of roles, he plays as a ten or off the left and we can decide on the day how we use him.
“I think you have to buy the right players then you might need players who need time to settle in.
“So of course we'd like to strengthen and of course, we want you to keep improving and challenge the teams at the top."
