Although Antonio Valencia's early strike and Jesse Lingard's brace ultimately secured a first win for United at the Emirates Stadium since 2014, De Gea's significant contribution can not be overlooked as the no.1 was in outstanding form between the sticks - beaten only by Alexandre Lacazette's strike early in the second half.

"I just know that Paul is frustrated and a bit disappointed with this colleague, Koscielny, with this kind of reaction".
"That's what you want, the players have produced a quality performance".
"I don't think anybody thought it was the wrong decision, but psychologically it sends a message to the fans, to us, and to the players that they're already thinking about a bigger fish to fry next week". We were too on the edge mentally maybe - you can not be in a game like that.

"Of course, they can say they had chances but we fought and we had a great goalkeeper too and I think we deserved it".
"That really set us up in a place which can be really intimidating, because Arsenal are known for their fast starts".
