A fight with a teammate is the reason Alexis Sanchez was dropped for Arsenal's Premier League loss to Liverpool over the weekend.
It's been revealed that the Chilean stormed out of training which led to an angry confrontation with team-mates in the dressing room.
Speaking after the game on Saturday, manager Arsene Wenger was standing by his decision to bench their best player:
"I don't deny that Alexis Sanchez is a great player, I bought him and I always played him and I think he has developed well with us.
"A decision like that is not easy to make but you have to stand up for it."
