Several hours before the second leg of the Champions League, fans of Benfica and Brugge fight.

The European Champions League encounter on Tuesday began with a depressing and unpleasant appetiser: a brawl between Benfica and Brugge supporters.

CNN Portugal said that the altercation happened early in the morning in Lisbon close to Estádio da Luz.

Two males were admitted to the hospital with minor injuries before being released, according to Portuguese media.

Due to the incident, the police were on high alert, which raised awareness of the departure at 17:00 (Brasilia time).

After the Eagles defeated Brugge 2-0 in the first leg in Belgium, the two teams will face again.

The Benfica supporters made a huge step towards clinching their place in the Champions League quarterfinals thanks to the fantastic performance achieved away from home.
