A Tottenham Hotspur supporter has been seriously injured and nine other fans hurt in an attack as they celebrated in Rome ahead of the Europa League match against Serie A side Lazio.
Police said the 10 - nine British and one American - were attacked outside a pub near the centre of Rome by a group of masked assailants.
One suffered injuries to an artery and is in a serious condition.
A police spokesman declined to identify the attackers but said a number of Italians who were involved in the fight had been detained.
