Jose Mourinho insists he is "not surprised" Pep Guardiola was not punished for encroaching on the pitch on Wednesday - as the Manchester United boss was earlier this season.
"He is very frustrated because everybody knows that Paul is a clean player and it was not his intention at all to be close to a red card".
They comfortably held on despite Paul Pogba being sent off for a unsafe challenge late on, punishing Arsenal for early defensive mistakes.
When asked if he felt unstoppable, De Gea told MUTV: "Sometimes, you just start a game with a really good save, with a good feeling, you feel that [unstoppable] but we started the game really well, we scored two important goals and it's true that we lost a bit of a control of the game after, but it was a good performance".
"The Neymar deal is special for me because it means journalists are not looking at the price any more".
"If it was hard, no; if it was mud, no - the pitch is absolutely handsome but I think they were a bit too much".
And according to Pogba, he is happy to have the moniker of "world's most expensive player" off his back, as it is allowing him to show his true colours on the field.
Pogba is likely to feature on Tuesday night when United will seek to secure their place in the Champions League knockout stages against CSKA Moscow.
Even so, Wenger acknowledged Arsenal had only themselves to blame for a loss that effectively ended their title bid. We were not decisive enough. And the 24-year-old enjoyed a successful first season back at Old Trafford as United tasted success in the Community Shield, EFL Cup and the Europa League.
