Arsene Wenger and Jose Mourinho in focus
Familiar foes Arsene Wenger and Jose Mourinho went toe-to-toe again as Manchester United secured a 3-1 victory in a pulsating game at Arsenal.
Early goals from Antonio Valencia and Jesse Lingard put Mourinho's men in control before Lingard sealed the win with his second after Alexandre Lacazette had halved the deficit for Wenger's side.
United had Paul Pogba sent off for a dangerous tackle on Hector Bellerin with 16 minutes remaining but they held on to end Arsenal's 100 per home league record this season.
Here, Press Association Sport looks at how the opposing managers fared at the Emirates Stadium.
Wenger's poor record against Mourinho has been much publicised. The long-serving Gunners boss, in his 22nd season in north London, had managed just one competitive victory and a Community Shield win over his Portuguese counterpart in 18 meetings ahead of kick-off. The only Premier League success came in May when United, with a Europa League semi-final on their minds, were beaten 2-0 at the Emirates. Thanks to a couple of dreadful errors helping United into an early 2-0 lead on Saturday, the Frenchman was always struggling to improve those head-to-head stats.
Wenger perhaps attempted to give Mourinho a taste of his own medicine in the build-up to the game, declaring striker Lacazette unavailable due to injury before promptly naming him in an unchanged team following Wednesday's 5-0 thrashing of Huddersfield. Whether it was mind games by Wenger or a miraculous recovery from the France international is unclear. United also enjoyed a resounding midweek win and Mourinho kept faith with the attacking line-up which won at Watford.
Mourinho, notably against Liverpool and Chelsea this season, has been accused of 'parking the bus' when playing the Premier League's top teams away from home. There was no sign of negativity from the Portuguese coach in the opening stages on Saturday evening though as United, who scored four at Vicarage Road in midweek, began brightly, attacking with pace and precision as they ruthlessly built a two-goal advantage. The Gunners responded well to the slow start which undoubtedly ruined their game plan and put United under heavy pressure, pegging them back inside their own half prior to the hosts adding a third on the counter attack.
There was a friendly handshake - initiated by Wenger - ahead of kick-off and, with the technical boxes at the Emirates a decent distance apart, the pair had little interaction during the game. Wenger was quite happy to ignore the constraints of the box, however, and regularly wandered along the touchline to talk to fourth official Anthony Taylor.
Both men showed plenty of emotion and passion throughout the match, with Wenger understandably the more agitated during the first half and Mourinho, who leaped off the bench in relief to celebrate the third, more concerned after the break. Mourinho was visibly incensed when, after Pogba was dismissed, Laurent Koscielny was only shown a yellow card after bringing down Romelu Lukaku with the Belgian racing towards goal.
Arsenal produced a superb performance for large parts of the game but Mourinho once again displayed the mentality of a winner by leading his side to an extremely hard-fought victory. The hosts enjoyed 75 per cent possession and had 33 attempts to United's eight, underlining the effectiveness of Mourinho's team. The one downside for the Portuguese, however, is that he will be without suspended midfielder Pogba for three games, including the Manchester derby.
