Three Ajax supporters were stabbed with one seriously hurt after fighting broke out before the club’s Champions League match against AC Milan on Wednesday night, Italian police have confirmed.

The Ajax fans fought with both opposing supporters and Italians demonstrating against Enrico Letta’s government in running battles throughout the day.

The supporter in the worst condition was knifed in the stomach and the others were wounded in the buttock and leg, a police spokesman said.

‘The one with the stomach wound is clearly the most serious but as far as I understand it’s not life threatening,’ he said.

All three were taken to Milan’s San Carlo hospital, while a local street salesman also suffered a minor knife wound in the scuffles but was not hospitalised.

Three Ajax supporters were arrested in a separate incident for trying to rob a street kiosk.

Milan qualified for the last 16 of the Champions League after a 0-0 draw in the San Siro on Wednesday night.

The home side had Riccardo Montolivo sent off by Premier League referee Howard Webb early in the match for a foul on Christian Poulsen but they clung on to qualify from Group H with Barcelona.
