Wantaway Arsenal striker Alexis Sanchez has posted a selfie to his Instagram page in which he claims to be "sick".

The social media update comes less than 24 hours after Arsene Wenger revealed he expected the striker to report for pre-season training on Sunday.

Arsenal play in the Emirates Cup on Saturday and Sunday this weekend but the Chilean is not expected to feature after being given an extended summer break after competing in the Confederations Cup.

Despite ongoing speculation linking Sanchez with a move away from the Emirates, Wenger said on Thursday that the 28-year-old is due back at training this weekend.
