Arsenal are on red alert with Mamadou Sakho fed-up at PSG.

The defender is highly-rated by Gunners boss Arsene Wenger and admits he's upset with his limited role at PSG this season.

"It's infuriating, frustrating, annoying to be on the bench," he told Le Parisien. "But I can't let the team feel my emotions.

"The most important thing is that PSG win and become champions. Then we can discuss my personal case later."
