Arsene Wenger finally gets one over arch-rival Jose Mourinho
Arsene Wenger has finally recorded his first league win over Jose Mourinho after 13 attempts against the Special One.
The pair have had a strained relationship in the past, with Mourinho branding the Arsenal boss as a "specialist in failure".
Before and after kick off the pair shook hands but it did not take them long until they clashed on the touchline as the Gunners cracked United's defence.
Red Devils' resilient defence crumbles
Manchester United were unfortunate when Xhaka's long range effort deflected off Ander Herrera and looped over David De Gea.
Then just two minutes and nine seconds later, they found themselves two goals down when Welbeck's thumping header punished his former side.
Welbeck has now scored three times in his last four matches against the Red Devils.
Mourinho set his side up extremely defensively and they were forced to change their mentality when they trailed by two goals.
But they were unable to get back into the tie, seeing an end to their 25-match unbeaten run.
Henrikh Mkhitaryan wasted in defensive system
Mourinho's defensive tactics saw Henrikh Mkhitaryan struggle to make an impact in the match.
It was clear the Red Devils were playing for a draw as the Armenia international and Mata were both playing deep - making it almost a back six for United at times.
But when they went two goals down, Mourinho brought on Jesse Lingard on the hour mark to replace Mkhitaryan.
