A Liverpool fan was reportedly stabbed ahead of Tuesday's Champions League semi-final first leg between the Reds and Italian giants Roma.
According to Daily Star journalist Jeremy Cross, paramedics were called to treat the victim following clashes between rival fans ahead of the clash at Anfield.
A group of around 20 Italian supporters are believed to have targeted the English club's supporters before police arrived on the scene.
The match on Merseyside has gone ahead as planned.
