There have been many famous footballing brawls at training grounds. Just last season there was reported unrest at Manchester City with Mario Balotelli and Roberto Mancini.
This week, Port Vale captain Doug Loft was left badly beaten after an alleged fight with a team mate and Swansea confirmed there was a coming together before the Chelsea game, but that they understood it.
In 2007, Joey Barton fought with Ousmane Dabo at Manchester City, leaving him with a black eye.
Why though, do Swansea understand it? Is it that time of the season?
That can be the only explanation, given their position in the league. The management did not condone the incident but during the stress of a Premier League season, clashes are bound to happen, but physical ones are very rare.
Could you imagine if Jose Mourinho hit one of his players? At Port Vale, the culprit may well be charged with Grievous Bodily Harm if found guilty of the attack. Some can most definitely be more serious than others.
Aston Villa have also confirmed that assistant managers Ian Culverhouse and Gary Karsa have been suspended, although the reason why is of yet unknown.
Joey Barton famously beat team mate Ousmane Dabo at Manchester City seven years ago, although the Englishman claims that Dabo was the instigator in the affair. This is the anomaly however, as there was no evident pressure at the time.
The 2002 World Cup saw Swedish pair Olof Mellberg and Freddie Ljungberg clash in training. The World stage clearly got to both of them, again in favour of the pressure cracking even the best players.
These bust ups can also happen in games too, as ex-Manchester United manager Six Alex Ferguson famously kicked a football boot above David Beckham's eye in 2003 after losing an FA Cup tie to Arsenal.
Even the greatest players crack under pressure and the immense stress of playing professional football at the highest level.
