Carlos Tevez has long been a loose cannon at Manchester City and, after refusing to play last night in the Champions League, Roberto Mancini looks to be at the end of his tether with the striker.
But Mancini can take comfort in the fact that while he may be facing a problem with one of his players, managers and footballers having bust-ups is nothing new.
Here, GMF looks back on five fights that will always be remembered.
Roy Keane v Mick McCarthy (Republic of Ireland, 2002)
Keane was never one to be subtle in his words or actions, and the Ireland international made his feelings over Mick McCarthy very clear in a war of words in the press. Keane wasn’t happy as Ireland travelled to the Saipan, with the midfielder reportedly not satisfied with the facilities. His tirade at McCarthy resulted in being kicked off the Ireland side while the manager was in charge.
“I didn't rate you as a player, I don't rate you as a manager, and I don't rate you as a person,” Keane said. “You're a f***ing w**ker and you can stick your World Cup up your arse. The only reason I have any dealings with you is that somehow you are the manager of my country! You can stick it up your bollocks.”
Craig Bellamy v Graeme Souness (Newcastle, 2005)
Bellamy was forced to play out of position for Newcastle, and a row with Souness ensued after it came out that the striker had faked an injury in protest. The media could hardly keep up with the player and coach’s comments, with Bellamy accusing Souness of being a liar, and the Newcastle board insisting that Bellamy thought he was bigger than the club.
One £80,000 fine later, Bellamy moved to Celtic on loan, and at the end of the season, after a string of further controversies with Toon teammates, he made a permanent move to Blackburn.
Sir Alex Ferguson v David Beckham (Manchester United, 2003)
After United lost to Arsenal in the FA Cup in 2003, Ferguson was even more angry than usual. Not content with merely yelling at Beckham, he kicked a boot at the England international, cutting him above his left eye.
While Beckham insisted that all was forgiven after the incident, he moved to Real Madrid that year. While Ferguson is well known for scaring players when they under perform, the Beckham incident seemed like proof that the Scot doesn't give anyone special treatment - not even Golden Balls.
Joey Barton v Alan Shearer (Newcastle, 2009)
Shearer had been appointed manager as a last-ditch effort to save the Toon from being relegated, and putting Barton on the pitch in a do-or-die game against Liverpool wasn’t the best decision he ever made. Barton was sent off for a straight red, and got into a massive bust-up with Shearer in the change rooms.
"You're a s*** manager with s*** tactics,” Barton reportedly said. Shearer didn’t last as manager, collecting just five points from a possible 24 in his time in charge. Tempers recently flared up between the two again when Barton tweeted of Shearer’s appearance on TV: "Bad shirt, shoes and views from Shearer again. Sort it out slaphead."
John Sitton v Leyton Orient (Leyton Orient, 1995)
This YouTube clip sums up a pretty scary manager. Sitton was livid after Leighton Orient went down 1-0 to Blackpool at half time, and sacked fan favourite Terry Howard on camera in his half time talk.
Sitton was co-manager of the club with Chris Turner, and after the club won just seven of 47 games with the pair, they were sacked in the same year as Sitton’s famous speech.
