Observers are claiming Arsenal boss Arsene Wenger and Alexis Sanchez refused to shake hands at training yesterday.

Video footage shows Sanchez head out for a session with team-mates ahead of the Gunners' Europa League clash with Red Star Belgrade.

Wenger extends his hand for Mesut Ozil while Nacho Monreal and Sanchez continue talking.

Sanchez steers clear of his boss but Monreal veers towards Wenger to greet him.
