The Manchester United boss has been speaking to Sky Sports after today's 3-0 win.
Here's what he had to say...
On knowing the Man City result...
"It is much too difficult [to stop them finding out] with the iPhones, iPads and television in the dressing room and it is against the culture I believe.
"The players are always looking to the other match so we must respect the culture and I adapt to that.
"I was also in former days coach of Barcelona and Real Madrid was always playing in front of us, but when we won we were top of the league.
"It is not so easy under pressure to be top of the league and I have to praise my players that they could win and beat Sunderland.
"We win again and score beautiful goals. so I am a very happy coach."
On Anthony Martial...
"I think he was one of the main keys why we have won this game so he is not only a goalscorer, he is a creator of goals.
"I am very happy with him."
On Wayne Rooney...
"For himself it is very important but for me it is not important, I don't care who is making the goals we have to make goals as a team.
"Personally I am very happy for him."
