Jack Wilshere is in a battle to be fit for West Ham’s crucial Premier League game at Everton on Sunday.
The midfield player, signed from Arsenal on a free transfer in the summer, has missed the last two days of training because of an injury to his left ankle.
He is desperate to be involved at Goodison Park as he fights to make an impact at West Ham.
Manager Manuel Pellegrini has spent £100million on new signings, but they are yet to make a significant impact at West Ham, who are bottom of the Premier League having lost all four of their opening matches, including home defeats by Bournemouth and Wolves.
After the trip to Everton, three of their next four games are against Chelsea, Manchester United and Tottenham. The other is a tricky away game at Brighton.
Pellegrini will be desperately hoping that the problem is not a recurrence of the serious ankle injuries that plagued Wilshere’s career at Arsenal.
The 26-year-old midfielder has missed more than 150 games through injury since his debut in 2008.
