The biggest bust-ups and feuds in sport including Formula One battles and biting of opponents

Shoaib Akhtar v Mohammad Asif

These two Pakistani cricketers clashed with each other during the Twenty20 World Cup in 2007 when a team net session got out of hand.

Allegedly Akhtar compared himself to the great Imran Khan, which led to an argument with fellow bowler Asif and the latter was hit with a bat.

The senior bowler was banned for 13 matches, fined £28,000 and sent home from the tournament.
