"The fans actually set us off".
"Over the last two weeks, we probably haven't got the rub of the green", he added.
The victory pushes Newcastle up to 13-place in the Premier League but Benitez's side are still in the thick of it as they sit just two points away from the last relegation place which is occupied by Southampton.
"It doesn't matter how many times City win the league or the way they play, Man U is Man U at the end of the day".
While Manchester United had some good chances in the game near the end, they were below par for so long that it did not feel as though the team deserved to take anything from the game. "Still we have 11 games to play".
"It would have been a tough fortnight if we hadn't have won".
"That's what they want and fair play to them - we need that every game and they give it to us every game".
"The way we were playing, with everybody giving everything, was absolutely fantastic".
Newcastle took the lead at Old Trafford in the reverse fixture before a rampant United side responded with four goals to claim all three points.
Rafa Benitez's side claimed their first home Premier League win in nearly four months on Sunday. Our hard work and endeavour was enough to get us over the line.
"In this case, we were pushing from the very beginning and challenging for every single ball". "They came here today to fight for a point, but they found themselves in a position of being 1-0 up and from that moment, they went over all the limits in terms of effort, sacrifice and everything a manager likes to see in his team".
The biggest disappointment was the build-up to the goal as Matt Ritchie was left with all the time in the world to slot home his first goal of the campaign, and post-match Lascelles was scathing of United's performance stating that most of United's went "missing".
Mourinho bemoaned his side's defending for Ritchie's victor, and contrasted his own players' lack of urgency in that situation to the frenzied effort that secured Newcastle all three points.
