Richard Keys branded Arsenal and Scotland defender Kieran Tierney an "idiot" after he had to be hauled off the pitch at full time against Leeds yesterday.

The former Celtic man was clearly incensed at the final whistle as he headed straight for Leeds star Ezgjan Alioski upon the end of the game.

Alioski had been the victim of a headbutt from Gunners ace Nicolas Pepe, but Tierney clearly didn't agree with his reaction to the flashpoint.

Emirates players and staff had to escort the Scottish youngster down the tunnel and broadcaster Keys wasn't impressed.

On beIN Sports' coverage of the match, the host said: "He just needs to get himself off now Tierney. He's just being an idiot. Get off!"

Nicolas Pepe’s behaviour was labelled “unacceptable” by Arsenal manager Mikel Arteta, who raised concerns at his side’s goal drought continuing as they came away from Leeds with a fortuitous 0-0 draw.
