Manchester United have long enjoyed superiority over Manchester City, but Monday's Premier League title showdown could signal the changing of the Mancunian guard.
City have already sampled Champions League football and are an expanding force bankrolled by the Abu Dhabi United Group. United are enjoying Sir Alex Ferguson's Indian summer, whilst owned by the loathed Glazer family.
Trash-talking, as the Americans call it, has begun again, but there were always the occasional digs from both sides of the Manchester divide.
Here we recall some of the most memorable City-United quotes:
“They’re a small club with a small mentality.”
Sir Alex Ferguson on that Carlos Tevez billboard.
"This club will, without doubt, be the biggest and best football club in the world. And it’s not a case of ‘if’ but when we are at Wembley having beaten Man United yet again."
Garry Cook, former CEO at City. The Citizens lost 3-1 and 4-3 on aggregate overall in the 2010 League Cup semi-final.
“I have more respect for Liverpool in a sense of their tradition and their history than I would do some of the other clubs that have been coming on the scene in the last few years, throwing a load of money at it.”
Gary Neville levels a thinly-veiled dig at the blue half of Manchester.
"There are three types of Oxo cube: Light brown for chicken stock. Dark brown for beef stock. And light blue for laughing stock.”
Former United manager Tommy Docherty cooks up the ingredients for what City are to him.
Laughing Doc
“There has been nothing to choose between us in the last five or six games. They will obviously be pissed off that they have only managed to beat us once and that game was a Carling Cup semi-final first leg, with us having another game to make up for it.”
Paul Scholes prior to the 2011 FA Cup semi-final. City won 1-0 and Scholes was sent off.
“The fans, the players and every single person involved with Man City FC were incredible today. Definitely the moral winners of this game.”
Vincent Kompany demeans himself after United edge past City 3-2 in the third round of the FA Cup.
Morally victorious
“We lost today but in our heads we won!”
Team-mate Micah Richards continues the charade.
“I think City fans are true Mancunians – 80 per cent of United fans are from Ireland, Scotland and God knows where.”
Manchester City’s 1976 League Cup-winning captain, Mike Doyle. One of the chapters in his autobiography was titled “Stand Up If You Hate Man U”.
Crouch down if you hate Man U
“They can say what they want. I won't say anything to them. I will be focused on the game. All that matters is the result, nothing else. After the game I might think about the supporters but not during it or before.”
Mario Balotelli prepares for a hot reception from United fans... and goes on to score twice in The 6-1.
"I'd waited long enough. I f*****g hit him hard. The ball was there (I think). Take that you c**t. And don't ever stand over me sneering about fake injuries."
Roy Keane gets revenge on Alfie Inge Haaland in the April 2001 derby.
“I didn't do myself justice after joining Manchester City but, having said that, I shared a house with George Best for two years so it had its compensations!”
Mick Horswill suggests sharing a house with a legend was as good as playing for City.
"We were the last Manchester team to win the League and we'll be the next one."
Former City chairman Peter Swales makes a grossly inaccurate prediction in 1992. United have won 12 titles to City’s 0 since.
You sure?
