The Hammers have signed five players so far this summer with Pablo Zabaleta, Joe Hart, Marko Arnautovic, Javier Hernandez and young prospect Sead Haksabanovic arriving in East London.
Slaven Bilic's recruitment has been markedly improved after some disastrous business last season.
The club has also been busy shipping out deadwood with speculation they are far from done in the window after a net spend of just £10 million.
The Hammers are widely regarded to be "winning the window" after snaring the likes of Chicharito for just £16m.
With the new signings comes added pressure to produce results.
It also creates selection dilemmas for Bilic who must now reconfigure his team in an effort to achieve better performances off the back of last term's 11th place finish.
So we're here to help, is this West Ham's best XI for the new campaign with everyone fit?
