West Ham have had a busy window and one more player could arrive, circumstances permitting.
West Ham manager Slaven Bilic
Bilic told reporters at his pre-match press conference ahead of his side's trip to Chelsea on Monday that he could be looking to bring in one more new player.
He has since elaborated a little in his column in the London Evening Standard, with the side's progress in Europe having a major bearing about whether a further deal will be done or not.

He wrote: "Maybe we go for one more in midfield if, hopefully, we qualify for the Europa League group stage but it won’t be a huge transfer."
European campaigns can put a few more demands on the squad. Given that Bilic has said it won't be a huge transfer, if the Hammers are to bring in another midfielder then the chances are they won't be the kind of player that starts every week, and is content to be a rotation option with the side dealing with a busy fixture schedule.

Bilic will be hoping his side can kick on from their impressive league campaign last season but also balance the commitments of playing in Europe for a prolonged run, which could provide a big challenge to his side.
It has been a pretty summer at West Ham with Arthur Masuaku, Andre Ayew and Jonathan Calleri all signing in the last week, and several areas have been strengthened throughout the summer.
