Swansea City boss Brendan Rodgers expects Manchester United to come back stronger next season.
Rodgers is certain United will be a formidable force next season.
"I have never been in the position City and United are in next week," he said. "It is so exciting. It is brilliant. You are talking about two great sides.
"The professionalism of Manchester United today was exemplary. They were probably watching the game beforehand and when Manchester City got those two late goals it could have really deflated them.
"Manchester United are serial winners. What makes them great winners is how they respond to not winning trophies.
"So if it is not for them this year, when you look at their history, they always come back the next year and win, so they will be there or thereabouts next season."
