Man City

Manchester City have lost five Premier League games in 2015, one more than they lost in the whole of 2014.

A terrible year.

Sunday Peter: For sixth time in eight games, City fell by the wayside. Appalling!

Tom Hutchings: Man City need to watch their backs, Liverpool have a game in hand, with their next four games being against Newcastle, Villa, WBA and Hull.

Belfast Kopite: Some Man City fans starting to sound like Chelsea fans of recent times. Sacking a Premier League-winning manager is not the answer!

Manchester United goalscorer Juan Mata said: "In the first 10 or 15 minutes City were brilliant but after that we showed character and came back. It was a massive result and everyone from United is happy.

"The atmosphere was crazy, it's something we will never forget. We have six games to go and have to keep going. It's one more step towards the Champions League, it's a big win and a boost to the confidence. But Arsenal are a great team and City and Liverpool will stay fighting until the end."

Jerry Aldini: Yaya Toure should have stayed in bed today. He played like he was still in it.

Stephen Shaw: 11 unpaid City fans would have given a better account of themselves.

Nathaniel Amoaku: Some good news for City fans. Sergio Aguero has remembered how to score.

Nick in London: If you'd done an 11 of "United misfits" earlier I'm pretty sure each scorer today could have been included. Just needed Bebe to come on and score a screamer to really top it off.

James Marshall: Louis Van Gaal certainly turned things around at Man Utd. Not sure I would trust him with the purse strings though.

Luke in Telford: United are so comfortable that they can afford to bring on the luxuries. Falcao and Di Maria's exclusions are proof that United have a team, not individual stars.

Manchester United will be looking at second place now, while City will be worrying about fourth.

Ashley Young collects his man of the match award, a sight that would not have seemed possible for most of the last season or two.

BBC Sport pundit Robbie Savage at Old Trafford

"You could see the reaction from supporters after the game the belief in the Manchester United fans. Louis van Gaal has really got the fans on board. This was a big test and they've passed it with flying colours."

BBC Sport pundit Robbie Savage

"This City squad has had its day. This is a point in City's future where they have to rebuild, and they have to change their manager. There has been complacency and tactically they have been poor as well."

Ashley Young echoes Robbie Savage in calling his team's win 'magnificent.'

Full reaction to come from all involved today.

BBC Sport pundit Robbie Savage at Old Trafford

"I think Manchester United were magnificent. It was a dominant performance and with the exception of Sergio Aguero City were very poor. Some great attacking play from United and Phil Jones and Chris Smalling were fairly solid at the back. They were deserved winners. Since that Tottenham game they have really grown in confidence."

A wonderfully eloquent text from Mike. The FA should sign you up.

Mike in Liverpool: "Not sure what this weekend's games tell us about the Premier League other than entertainment takes precedence over quality. Defence, never high in the minds of British clubs, is receding in its relative importance. Our clubs have struggled in Europe due to defensive naïveté and tactical ineptitude. Chelsea have the Premier League's most balanced and quality squad but were found out in the Champions League.

"As an Arsenal fan I see my team flatter to deceive every year when the pressure is off and we are already out of the knock out phase of the Champions League. When this happens year after year it signifies a need to strengthen. This is true for all English clubs. Buying big doesn't always equate with buying quality. It brings questions about building squads, tactical flexibility, defensive preparation and sometimes pragmatism. The problem is some of these will come at a cost of entertainment - the cornerstone of the Premier League's success - never mind the quality, feel the excitement!"

A stroll in the Sunday rain for Manchester United. City were excellent for 15 minutes and dismal for 75.

Could they even finish outside of the top four? At this rate they could. That's six defeats in eight games in all competitions.

How many of this Manchester City side will be at the club next year? Despite protestations from inside the club you feel a major clearout is just what they need.

Sergio Aguero has now scored 100 goals for Manchester City. There are three minutes added on. Another City goal would make life interesting...

BBC Sport pundit Robbie Savage at Old Trafford

"It's great movement from Sergio Aguero for the goal. It's a consolation but still not enough from Man City today. He's been the bright spark for City."

Peter Collins: Manuel Pellegrini can't motivate the players? It's the Manchester derby, they shouldn't need it! Not his fault players are lazy.

David Simpson: Overpaid players at City. Just doesn't give room for passion. They showed no respect for this occasion.

Blackburn Lad: It's all very well saying sack Manuel Pellegrini but who would City get to replace him? Bit of a poisoned chalice.

A consolation, which is no consolation. Pablo Zabaleta gets forward for possibly the first time all game and cuts back for Sergio Aguero, whose shot goes in off the post and via the hand of David De Gea. Zero celebration.
