Olivier Giroud's powerful late header secured Arsenal a fortuitous draw as they rode their luck to snatch a point at Manchester United.
United have spent much of the international break in the headlines, whether for manager Jose Mourinho's treatment of Chris Smalling and Luke Shaw or captain Wayne Rooney's late-night antics when away with England.
Such issues looked to be behind them as Juan Mata gave United a deserved lead, only for substitute Giroud to power home a header in the 89th minute that saw Arsenal grab a 1-1 draw. It was their first and only attempt on target.
Mourinho will be furious after United slipped to a third successive home league draw for the first time since 1992, with the extension of his stranglehold over Arsene Wenger counting for little. Wenger has still never beaten a Mourinho side in the league.
Tweet of the Match
"Zero shots on target. ZERO. But hey, Wenger's right - we don't need a world class striker. #MUFCvAFC" - Arsenal fan Piers Morgan. They scored moments later.
Juan Mata: Always seemed one of the players most likely to make a difference, and so it proved as he arrived in the area at the right time to break the deadlock after 68 minutes. The Spaniard was strong and influential in attack until being taken off five minutes from time.
Chants of the match
Wayne Rooney's return to action was greeted with warmth and humour by the United supporters, who chanted "Rooney's on a bender" as he came on to replace Anthony Martial. This was the start of a notable change in atmosphere with United fans becoming more vocal and Juan Mata's goal coming soon after. Prior to this, one of the loudest chants had been when Arsenal supporters told Jose Mourinho that he is "not special anymore". A rather more crude version of this chant was sung after Arsenal's late equaliser.
Surprise of the match
The biggest surprise was perhaps that Arsenal found a way back into the game to gain a point. Throughout the second half their attack had been blunt and they looked short of ideas after falling behind. The late introductions of Alex Oxlade-Chamberlain and Olivier Giroud made a big difference, however.
