Arsene Wenger defended Alexis Sanchez after an incident late on in Arsenal's narrow win over Leicester on Wednesday night.
The Gunners needed an 86th-minute Robert Huth own goal to see off the reigning Premier League champions and keep alive their hopes of a top-four finish.
After Huth had inadvertently deflected Nacho Monreal's late effort past Kasper Schmeichel, Sanchez was attempting to prevent a long throw-in from Christian Fuchs as the Foxes chased an equaliser.
Having refused to move away from the touchline, Sanchez theatrically hit the ground holding his face as Fuchs took the throw, seemingly aiming the ball at the Chilean.
