West Ham boss David Moyes admits he'd like to add depth to his squad this month.
Moyes says their active in the January market.
He said: "We'd like to add to our squad if we can and if we can find players who we think are suitable, we could do with some back-up if we can get it.
"There's never any guarantee in January the right players are gettable, but we're certainly looking around."
Moyes has also praised Jarrod Bowen, who scored his sixth goal of the season in the FA Cup win against Leeds.
"Jarrod's improvement in the two years he's been here has been brilliant," said Moyes.
"Some players from the lower leagues take time. Jarrod started near enough right away but has taken his game on to another level, and he needs to keep it up.
"I think he can do what he wants, he can play even better, but he's doing a great job for us just now."
