"The fans of "Porto" mocked the "Benfica" goalkeeper by releasing a chicken onto the field (VIDEO)" © EuroFootball.com

The match of great interest in the Portuguese championship was not easy for the stadium maintenance staff - they had to catch a live chicken thrown onto the field by fans.

The fierce encounter between the rivals - Porto and Lisbon's Benfica clubs - ended in an impressive 5-0 victory for the home team. After the win, Porto's team pulled away from their closest pursuers and lead by 10 points.

With the score at 3-0, the victorious fans did not miss the opportunity to mock Benfica goalkeeper Roberto. In Portugal, a careless mistake is called "frango," which means "chicken." That's why a live animal was released towards the goalkeeper, causing a headache for the staff trying to catch it. Additionally, the fans also threw golf balls at Roberto.
