LONDON (AFP) - Manchester United defender Patrice Evra and Chelsea groundsman Sam Bethell have been charged with improper conduct following a post-match brawl at Stamford Bridge last season.

Evra briefly traded blows with Bethell following Chelsea's 2-1 win over United on April 26 when members of the London club's groundstaff demanded that several United players, including the French defender, stop their warm-down on the pitch.

The United players refused to leave and an angry row broke out between the stars and Chelsea stewards and groundstaff.

Now Evra will have to answer the FA charge, while Bethell has also been charged with using abusive language aggravated by reference to nationality/race.

The FA, who took witness statements during their investigation, could hit Evra with a range of punishments including a fine or ban.

No date for the hearing has been set and with both clubs on pre-season trips, it may be a while before it is arranged.

"The charges are the result of a thorough investigation conducted by the FA over the last three months," an FA statement read.

"In bringing the charges, the FA used video evidence, CCTV footage and various witness statements from individuals present."

United defender Rio Ferdinand has been reminded of his responsibilities to the game following a separate incident, also after the Chelsea match, when he accidently kicked a female steward in frustration while walking down the players' tunnel at Stamford Bridge.
