A Spurs fan is believed to be critically ill following a stabbing when supporters were reportedly attacked in an Italian pub by a band of Lazio fans.
It is believed two people were stabbed and eight people have been injured by trouble-makers wielding knives and baseball bats.
One fan is believed to be critically ill.
Chaos is thought to have been sparked at the Drunken Ship pub in Rome ahead of tonight’s Europa League game between Tottenham Hotspur and Lazio.
The club is due to release a statement later today.
