Tiger Woods of the USA and Sergio Garcia of Spain stand on the 11th tee during round three of THE PLAYERS Championship …
After Tiger Woods and Sergio Garcia finally buried the hatchet with a handshake prior to practice at the US Open, we thought we would look back on some of sport's most famous feuds.
Woods and Garcia have never been the best of friends and an unwise comment from Garcia about "fried chicken" soured relations even further.
However, sport's long history is full of even more bitter feuds, encompassing wars of words and even outright violence.
Here is our pick of the most memorable personal duels.
1. Alain Prost v Ayrton Senna
The rivalry between the pair first intensified when Senna joined Prost at McLaren ahead of the 1988 season. The then twice world champion Prost was expected to be the main man, but Senna had other ideas: during that year's Portuguese Grand Prix Senna tried to block an overtaking attempt from Prost that nearly ran the Frenchman into a wall. In 1989 things got nastier still as Senna broke an agreement that the two would stay out of each other's way in the San Marino Grand Prix, while at the final and deciding race in Suzaka the pair collided at a chicane when Prost blocked an attempted pass from Senna.
Ali's astonishing powers of eloquence always seemed to desert him when the subject of Frazier came up. He resorted to branding him "dumb", and "Uncle Tom", and laid into his appearance on more than one occasion: "Frazier is so ugly that he should donate his face to the US Bureau of Wildlife," was just one such epithet. Frazier has never forgiven Ali for his cruelty "I hated Ali," Frazier said in 1990. "God might not like me talking that way, but it's in my heart." They fought three times, Ali winning twice.
Figure skating was the unlikely breeding ground for one of the most sensational stories sport has ever seen. On the eve of the 1994 US Figure Skating Championships in Detroit, Kerrigan was struck by an assailant with a baton and was forced to withdraw from the national championship, with Harding taking the title. It transpired that the attack had been orchestrated by Harding's ex-husband and Harding herself was later convicted of conspiracy to hinder prosecution.
"Mick, you're a liar … you're a f*****g w****r. 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. You're a f*****g w****r 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 b******s." What a way for the Ireland captain to withdraw from the 2002 World Cup following arguments over Ireland's facilities and training in Saipan. The two men later made up - though not after long and bitter recriminations.
Two of NBA's biggest stars were team-mates at the LA Lakers from 1996 to 2004 and won consecutive titles from 2000-2002. However, the two giant egos were never compatible as both felt they were the true leaders of the team. After some bitter exchanges behind the scenes, Shaq was eventually traded to the Miami Heat in 2004. He said of Kobe: “In the seven or eight years we were together, we were never together.”
The two American tennis stars clashed frequently on the court as they developed one of the sport's most intense rivalries. Connors once branded his opponent as "that f*** face McEnroe" but lost the sporting battle with 13 wins to McEnroe's 20 in head-to-head encounters.
David Peace's the Damned United paints a vivid picture of a fictional Clough's obsession with Revie, but the reality was just as compelling. Clough disliked Revie as a man and disliked the way in which his teams played the game. After replacing his rival as Leeds manager in 1974, Clough famously told his new players: "You can all throw your medals in the bin because they were not won fairly." He lasted 44 days in the job.
The rivalry between the two boxers was legendary, hatred spilling out from both middleweight fighters. On November 18 1990 they produced an enthralling bout that drew on deep wells of antagonism with Eubank winning via stoppage in the ninth round. Both men gave everything and a rematch in 1993 was also gripping, ending in a draw. As Barry McGuigan said: "There was real antipathy and ill-will there. But what fights, what fights."
Lewis was the golden boy of athletics in the mid-80s but the emergence of Johnson gave him a formidable rival. Their two personalities clashed and things came to a head when Johnson ran the fastest ever time of 9.79 seconds to win the 100m gold medal at the Seoul Olympics in 1988 but later tested positive for steroids in a huge scandal. Johnson has admitted using performance-enhancing drugs but in 2006 claimed Lewis had conspired to sabotage his sample with stanozolol.
