Arsenal sees VAR in London's der derby: It's coming through the upper hand because the action is seen by a machine.

Arsenal has passed the upper hand against West Ham, in the fair fight for 29th week at Premier League.

Alexander Lacantet made it in the 80th minute, but his note had to be analyzed microscopically by the VAR.

Pierre-Emerick Aubameyang's blow went wrong, ending up in the head of Mesut Ozil in the area, with the Turkish-German who assisted with his head for the Frenchman.
