Arsene Wenger has downplayed the tantrum from Alexis Sanchez when he was subbed out of Saturday's match.

Sanchez was upset at Wenger when removed with 11 minutes remaining in the match.

Sanchez immediately showed his displeasure with the decision as he trudged angrily off the pitch and kicked his own glove into the air as he walked to the dugout.

He then sat down away from his other teammates and pulled a jacket over his head instead of watching the final minutes of the match.

Wenger dismissed questions about the reaction of Sanchez, who has yet to sign a contract extension with the club despite ongoing talks.

"Looking at the game tonight, that is really minor, minor, minor," Wenger said. "All players are frustrated when they come off -- some show it, some don't. I am long enough in the job to know that. I just make the decision I feel is right and that's it. Nothing more than that.

"He's a good guy who gives a lot and wants to do well, always, for the team. There is no problem. But every culture is different. Some South Americans are a bit different to Europeans, Southern Europeans are different to northern Europeans. You have to respect that. That's why we are a multi-national team."
