Liam Gallagher celebrated Manchester City's triumph over arch-rivals Manchester United by bursting into the club's media room and declaring his love for manager Roberto Mancini.
The pop superstar, who watched City leapfrog United to go top of the Premier League following their 1-0 derby win, made the surprise appearance after Sky Blue's boss Mancini had given his post-match press conference last night.
Gallagher, an avid City follower, announced: "I love Mancini, he is nearly as cool as me."
The former Oasis frontman also delivered a cheeky jibe to United manager Sir Alex Ferguson.
Hinting why the Red Devils lost the derby that was billed as the most important game of the season, he said: "Ferguson must have been on the whisky."
Beady Eye singer Gallagher also posted a picture of himself with football legend Diego Maradona on Twitter following City's triumph.
The Argentinian had been at the Etihad Stadium to cheer on son-in-law Sergio Aguero, who helped lead City to victory.
Gallagher, who is pictured shaking Maradona's hand, added the caption: "Maradona shakes the hand of God!" in reference to the goal the Argentinian scored against England in the 1986 World Cup.
The pop star has been a regular supporter at City's home games over the course of the season, often pictured in a Sky Blue shirt alongside his sons.
Around 47,000 fans flocked to the Etihad Stadium to watch the sell-out clash while thousands more watched in pubs and bars around Manchester.
Greater Manchester Police said officers made a total of 31 arrests in the city centre and in or around the ground.
The majority of those detained were held for minor drink-related and public order offences.
The force said there were no serious incidents of disorder and no reports of any trouble taking place in other areas in Greater Manchester in relation to the derby.
Chief Superintendent John O'Hare, commander for the derby policing operation said: "With so much resting on the game, this derby was always going to be an exciting match with emotions running high.
"Thousands of people were out in the city and towns across Greater Manchester to soak up the atmosphere and I must praise the behaviour of the supporters from both sides. Their conduct was exemplary and they enjoyed this fixture in the true spirit of the game.
"We had a lot of extra officers working throughout the day, supported by partner agencies, to ensure this match was an enjoyable experience for all football fans and I am pleased to say there were only a relatively small number of arrests."
Councillor Jim Battle, deputy leader of Manchester City Council, said: "With the eyes of the world on Manchester, two great teams showcased our great city at its very, very best.
"I'd like to praise both sets of fans for their excellent behaviour and thank the police for their well-planned operation."
