A man is in hospital with serious injuries following an 'unprovoked' attack after Sheffield United's game v Grimsby.
The 46-year-old, who attended the match alone, suffered multiple injuries as he walked home after the final whistle.
The self-employed electrician was walking along the sea front in Cleethorpes when he was attacked.
The badly injured victim was found by police officers on grassland at around 5.45pm after Saturday's game.
He was wearing a distinctive anorak-style silver jacket and blue jeans at the time of the attack.
Officers want to hear from anyone who remembers seeing him or who witnessed the attack.
Sheffield United and Grimsby fans clashed in Cleethorpes after the game, with two police officers suffering injuries as violence flared.
Bottles and other missiles were thrown during the fighting and damage was cause as fans ran amok.
Three Sheffield men and one Grimsby man have been charged with assault, affray and public order offences.
