Shkodran Mustafi's header denied Manchester City a chance to move up to third in the Premier League as Arsenal earned a 2-2 draw at Emirates Stadium.
The Germany international glanced Mesut Ozil's corner past Willy Caballero to leave sixth-placed Arsenal within seven points of Man City in fourth.
The match got off to a blistering start, with Leroy Sane latching on to Kevin De Bruyne's through ball, rounding David Ospina and slotting in Man City's opener on five minutes, moments after Danny Welbeck fired narrowly wide.
Theo Walcott levelled following Mustafi's header into the penalty area on 40 minutes, before Sergio Aguero's drilled effort from a tight angle put City back in front before half-time.
Aguero missed with a free header soon after the break, and Arsenal capitalised with Mustafi's leveller.
