Arsene Wenger has been left with a goalkeeper crisis ahead of the Gunners' clash against West Ham on Wednesday, as per the ​Mirror.

First-choice goalie Petr Cech is still sidelined with a calf problem​ and could be out for two more weeks at the very least, and stand-in stopper David Ospina is now said to be feeling the effects of a heavy fall he suffered during the 2-2 draw with Manchester City on Sunday.

Wenger has 24-year-old Emiliano Martinez left at his disposal, and he will likely turn to the Argentinian for the West Ham match, as well as upcoming fixtures against Crystal Palace and Middlesbrough.

Martinez has made three appearances for Arsenal this season, with all of them coming in the EFL Cup. He can't be classed as inexperienced, but with Andy Carroll set to prowl the Gunners' box, it certainly presents a worry for the struggling side.

Ospina, meanwhile, could leave the Emirates at the end of the season. Ligue 1 side Marseille are reportedly set on signing the Colombian this summer, while several Turkish clubs are also believed to be keen.
