Mark Clattenburg has accused former Chelsea star John Obi Mikel of trying to punch him amid his row with the club in 2012.
The ex-Premier League referee, 50, says Mikel burst into his dressing room at Stamford Bridge after a heated match between Chelsea and Manchester United in October 2012, during which he was accused of a racial slur.
Chelsea alleged that Clattenburg had called Mikel a 'monkey' during the match but he was subsequently cleared by the FA, while the midfielder was later banned and fined £60,000 for threatening the official.
Now Clattenburg has speculated that Chelsea were just trying to get 'payback' after their captain John Terry was banned for an incident involving QPR star Anton Ferdinand in a game the year before.
