Rome - At least three people were stabbed in a brawl Wednesday between Lazio and Sevilla fans in Rome, with one suffering serious injuries, Italian media reported.
Two Spanish fans and an American were hurt in the fight, which broke out ahead of Thursday's UEFA Europa League match, La Repubblica daily said.
"Everything was quiet, when suddenly we heard shouting and the sound of broken glass. We rushed to the window and saw guys with hoods armed with clubs and batons that were attacking other guys," one local bar owner told the daily.
Some forty people were involved in the clashes in Monti in the historic centre, which was broken up by police in riot gear, it said.
The Corriere della Sera daily said one of the injured fans dragged himself bleeding along the street to call for help from passersby.
The Gazzetta dello Sport put the number of people being treated in hospital for stab wounds after the attack at four.
