Magistrates in Manchester handed conditional discharges to two of the men. A third was bound over to be of good behaviour while the fourth pleaded not guilty to possessing an offensive weapon.

He was bailed to return to trial in the north-west English city on June 28.

Twelve English fans were also charged after violence flared briefly between up to 100 rival fans outside the Old Trafford stadium in Manchester before Tuesday evening's game, which United won 7-1.
