Mauro Zarate is injured at the moment, but there are doubts whether he will be back in the West Ham United starting line-up when he recovers.
The Argentine forward has had a mixed start to the 2015-16 Premier League campaign, playing well against Arsenal on the opening day of the season but struggling to make an impact against Leicester City.
The 28-year-old is a good player, and manager Slaven Bilic will have to maintain faith in him once he is available for selection.
Things have not gone according to plan for Zarate at West Ham since his move in the summer of 2014, but he is a player who can make a difference for the London outfit in matches.
Many are surprised that Andy Carroll is still a West Ham player, with the striker having struggled with injuries for the past two years.
The former Newcastle United and Liverpool striker is on the verge of returning to action, and Bilic needs to make the best use of the Englishman.
The England international is far from guaranteed a place in West Ham’s starting line-up, but he is a player with Premier League experience who will come in handy as the season progresses.
