Tottenham supporter Michael Voller, 23, was brutally attacked by his own fans after last weekend's FA Cup semi-final between Spurs and Chelsea at Wembley, suffering a fractured skull, cheek-bone and eye-socket.
The young Spurs fan was punched in the face in a completely unprovoked attack, causing potentially life-changing damage to his eye-sight and skull.
The incident occurred at 7:30pm outside the Moore Spice Restaurant near Wembley Stadium, with the attacker mistakenly believing that Voller was a Chelsea supporter.
The suspect has been described by police as a white man in his early 20's who was wearing a black hooded jacket.
Although Voller has been discharged from hospital, Police say that he faces the prospect of permanent damage to his eye-sight.
As quoted in the Mirror , Detective Constable James Robb, of Brent CID, said: "This was a violent and unprovoked assault that has left a young man with some terrible injuries that could end up affecting him for the rest of his life.
"This kind of violence has absolutely no place at a football match, and I sincerely hope that those who were with the person responsible do the right thing by Michael, who is a fellow supporter and has supported Tottenham since he was a young boy.
"I’d appeal to all Spurs fans to think hard about whether they have any information about the person who did this. I’ve no doubt that there will be several people who know who did this and I would appeal to anyone with information to get in touch with us or to contact Crimestoppers anonymously."
Anyone with information regarding the assault or the identity of the suspect should contact Brent CID on 020 8733 3737 or call Crimestoppers anonymously on 0800 555 111.
