Alexis Sanchez sick note could derail Arsenal return

Alexis Sanchez’s start to the season could be derailed after the Arsenal forward posted a picture on social media claiming he was ill.

The Chile international has yet to begin pre-season training with his team-mates following his exertions at the Confederations Cup in Russia, where he helped the Copa America champions reach the final.

Sanchez’s future remains up in the air as he enters the final season of his current contract, with talks on a new deal seemingly at an impasse.
