Arsenal hero Martin Keown is demanding Mesut Ozil be sold in January.

Ozil came off the bench for Danny Welbeck on the hour mark at Watford and saw his side concede twice to go down 2-1.

“The top players are ruthless and they don't play for fun," Keown said on BT Sport.

“I don't know if he's got that ruthlessness in his makeup.

“That ball has got to be in the back of the net. That should be game over, Arsenal have won the game.

“People might think I'm gunning for him, but you've got to be clinical in those situations.

“Is he really bothered there? Look at that, he's just missed a chance to win a game for Arsenal.

"There's only one outcome here. When it comes to January surely Mesut Ozil will be gone."
