It is claimed the trouble was started by some Linfield supporters after the Irish Cup semi-final with Cliftonville.
Reports suggest some attackers wore neo-Nazi gear and had English accents.
The victim's father-in-law said his injuries were horrific.
"He was on a life-support machine and for a time, we didn't know if he was going to live or die," he said.
"His throat has been cut, his face has been badly beaten, he has head injuries with stitches on his nose and is very badly bruised.
"He wasn't breathing when he arrived at hospital, and is very heavily sedated."
Linfield bosses have said it has not been confirmed that club supporters were involved in the attack.
The Loyalist paramilitary community in Belfast enjoy a life unchallenged by unionist politicians while still armed.
They have been caught distributing neo nazo leaflets through letterboxes and there has been an increase in neo-nazism recently with a lot of graffity in Belfast.
Neo-naizi's have joined in loyalist marches also.
This seems to be another sad disgraceful growing problem on the streets of Belfast which judging by the accents of the attackers could have over seas links to neo nazi groups.
