Micah Richards has revealed that Samir Nasri had the "biggest argument" he had ever seen when he tried to square up to Roberto Mancini before the Manchester derby in 2011.
The Italian had set out how he wanted his Manchester City team to play before their trip to Old Trafford and were planning certain routines, such as set pieces. It's a normal thing to do before matches, with Mancini ensuring his side were as prepared as they could be before playing Manchester United.
However, after a while, Nasri's patience snapped and it caused a huge altercation between the pair. Richards admitted that the Frenchman offered to fight Mancini after a tasty encounter on the training field.
