Famous sporting squabbles

The Azerbaijan Grand Prix was set ablaze with as Sebastian Vettel and Lewis Hamilton clashed on the tracks. Vettel accused Hamilton of purposely 'brake-testing' him behind the safety car and promptly pulled alongside the Briton and rammed into his Mercedes. Hamilton branded Vettel's actions "disgraceful" and "disgusting" after the race, while Vettel protested his innocence. Here is a look at some of the other famous sporting squabbles. Hint: Hamilton leads the list. Photo: Getty Images
Lewis Hamilton and Nico Rosberg went from being the best friends to becoming the worst of enemies. Two of motorsport's biggest names rose through the karting ranks together before making the breakthrough to the pinnacle, Formula One. However, their friendship was put to the test during a bitter battle for the world title at Mercedes last year, with Rosberg eventually coming out on top. Photo: Getty
The flamboyant duo have been involved in bitter online dues and in the media over the years. They finally confirmed this month that they would clash in the boxing ring in August. It is a fight that splits opinion but is a sure-fire money spinner for both men, even if most believe UFC star Conor McGregor stands no chance. Photo: Getty
Justin Gatlin was a villain in the eyes of many after the American served two bans for doping and most hoped for Bolt to come out on top whenever the two met. Gatlin poured fuel on the fire by claiming Bolt had been given "a medical pass" to compete ahead of Rio 2016. Bolt promised Gatlin would feel his "full wrath" in Brazil and stormed to 100m gold, with Gatlin second.   Photo: Getty
Football managers often talk of their players being up for the fight, but team-mates Lee Bowyer and Kieron Dyer obviously took those words too literally when Newcastle United faced Aston Villa in April 2005, exchanging blows on a miserable afternoon all-round for the Magpies, who lost 3-0.

Kevin Pietersen's first misdemeanour came during the home series with South Africa in 2012, where he was accused of sending derogatory text messages about then captain Andrew Strauss and head coach Andy Flower to members of the opposition team. He was later reinstated into the the squad, but things once again got heated following England's humiliating 5-0 Ashes defeat in 2013-14. Pietersen was sacked following claims he was a bad influence on the team and he later released a book criticising several of his team-mates, Flower and even the ECB. Photo: Getty
