Ibrahimovic's way of celebrating - pour a drink on a colleague's head (VIDEO) © EuroFootball.com

How to celebrate victory in the Italian championship? Well, just ask Antonio Cassano. That's the logic followed by the controversial striker Zlatan Ibrahimović.

After securing the first place in the "Serie A" championship, the players celebrated on the field. Cassano gave an interview to one of the television stations, and Ibrahimović unexpectedly tapped him on the head.

Cassano didn't seem very pleased, but he seemed to take his teammate's strange actions as humor.

Let's remind that Ibrahimović is already famous for his peculiar behavior: once in training, he unexpectedly tapped Rodney Strasser out of nowhere.
