word is Manchester United players will tell club lawyers that Saturday's post-match battle at Stamford Bridge escalated when a member of Chelsea's staff called Patrice Evra a "f***ing immigrant"

the Guardian claims that 'senior sources at Old Trafford confirmed yesterday that one of Evra's associates had informed them the French defender was subjected to what Carlos Tevez described as a "grave insult"'

the Daily Mail goes further and suggests that 'at least two United players claim they heard the insult' from Chelsea groundsman Sam Bethell, who has denied all accusations of racism

'Chelsea sources' told the Mail that Bethell called Evra a "f***ing idiot", though they also claim that the comment was only made after the pair had exchanged blows and that Evra himself may not have heard the alleged insult
