The Frenchman recorded a first Premier League win over Mourinho at the 13th attempt as goals from Granit Xhaka and United old boy Danny Welbeck secured a 2-0 victory for the Gunners on Sunday.

Xhaka, who shook off an ankle issue to play in the clash at the Emirates, opened the scoring in the second-half after his long-range strike struck Ander Herrera and looped over goalkeeper David de Gea.

They play the second leg of their semi-final against Celta Vigo, which they lead 1-0, on Thursday. I think they will be okay because of the fact it is a completely different competition. We knew we had to win, we played a good game and deserved it too. Hopefully it gives him confidence.
"We still have a chance mathematically and we need some help as well from teams around us", Wenger said.
"Mourinho has only signed four players for Manchester United, once he's signed eight to 10 and he is a year further forward I'd be asking the question then if he's still playing a back six".
