With the summer transfer window now done and dusted, managers and players alike know where they stand until January.
West Ham were one of the busier teams in the window, as manager Slaven Bilic sought to add a number of new faces to his squad that he believes will compliment the attractive football he is trying to bring to the club.
With those arrivals taking precedence, several of the older guard now face uncertain times over their playing time this season.
We decided to take a look at the three West Ham players who will have to up their game to be first team regulars this season and beyond.
After impressing at West Brom in fits and bursts, Amalfitano has done a similar thing at Upton Park. The talent is there, but it seems the application is consistently missing.
With both Dimitri Payet and Manuel Lanzini coming in this summer to play in his favoured number 10 spot this season, he finds himself far down the pecking order in manager Slaven Bilic’s eyes.
Similar to Amalfitano, it is the competition for places which will likely see Zarate struggle for a starting spot this season.
He impressed in the win over Arsenal, grabbing the second goal, but his failure to perform consistently while the likes of Payet looks like he will be a regular star, means the choice is an easy one for Bilic. Zarate may have to accept cup games and substitute appearances from here on in.
The forward has failed to hit the ground running at West Ham, with a number of injuries having limited his game time severely.
He is a big player when he stays fit, offering the side something different with his power in the air and physical presence. However, he cannot be relied on to stay fit, and with Diafra Sakho, Enner Valencia and now Nikica Jelavic all ahead of him, he may struggle to get into the side even when he does return from his latest injury.
