We all know the game of football can easily set tempers racing and it has even been known to cause team-mates to turn on one another.
Top Corner looks back at some of the best 'bust ups' when players from the same side have seen red both on the pitch and the training ground. Handbags? Here's our very own bunch of fives...
Hartson v Berkovic
At first, West Ham boss Harry Redknapp described this incident in 1998 as 'handbags' but this image proves otherwise. Hartson was banned for three games for this sickening kick in the head while Berkovic couldn't eat for two days.
Adebayor v Bendtner
If watching your side lose 5-1 (not to mention 6-2 on aggregate) to your bitter local-rivals wasn't enough, seeing two of your players pathetically turn on one another really does take the biscuit. This was exactly what Arsenal fans had to endure when suffering at the hands of Tottenham in a League Cup semi-final in 2008. It was reported that Adebayor had said to Bendtner "I'm on because you're s**t" before aiming a head-butt towards the Dane but the now-Spurs striker later revealed it all came about because Sir Nick was wearing trainers in the dressing room...makes sense.
Batty v Le Saux
Think Blackburn Rovers in the Champions League, think David Batty and Graeme Le Saux. In 1995, the two had fallen out prior to an away game against Spartak Moscow and tempers soon boiled over on the pitch when Batty accused Le Saux of not passing him the ball. Although it was only Le Saux who actually connected with a punch, the Jersey-born left-back still managed to come off worse as it was enough to break his hand. Rovers lost the game 3-0 in what was a massively embarrassing night for the Lancashire club.
Balotelli v Mancini
Mario Balotelli's time at Manchester City, as we all know, was shrouded in controversy but perhaps one of the most memorable moments and one which may well have been the final nail in his City coffin, was the training ground bust-up with manager Roberto Mancini. The incident happened at the beginning of January in 2013 and by the end of the month, he was sold to AC Milan.
Bowyer v Dyer
Kieron Dyer recently revealed that after this on-pitch scuffle with Newcastle team-mate Lee Bowyer, manager Graeme Souness offered to fight both players in the changing room after the game. Needless to say, neither took him up on the offer. Seeing as this is our favourite example of when team-mates go to war, we thought you'd like to see it again...enjoy!
