Alexis Sanchez will undergo a late fitness test ahead of Arsenal’s Premier League clash against Stoke this weekend.

Arsene Wenger gave an upbeat assessment on the Chilean’s fitness ahead of the Gunners’ trip to the Britannia Stadium on Sunday but the manager admitted that it would be a “gamble” to play the forward.

Sanchez has suffered a series of setbacks in his increasingly complicated recovery from a hamstring injury that has kept him out since late November.

But Wenger was cautiously optimistic in his pre-match press conference on Friday morning.

Asked for the latest on Sanchez, Wenger said: “He has two decisive days. Today and tomorrow. He’s fit. Do we take a gamble or not on his injury?”

Sanchez forward had been pencilled in to return for Arsenal in their FA Cup clash against Sunderland last Sunderland after being out since 29 November, when he went off with a hamstring injury in the 1-1 draw against Norwich at Carrow Road.

But he suffered another setback, which came after he previously missed the win over Manchester City on 21 December that had initially been targeted for his comeback.

Arsenal’s match after the trip to the Britannia Stadium is the landmark clash against Chelsea, which takes place at Emirates Stadium on 24 January.
