VIDEO: Ronaldo mocks Lustig after headbutt

Portugal will take a 1-0 lead into the second leg of their World Cup play-off versus Sweden.

Cristiano Ronaldo, as he so often is, was the difference, scoring in the 82nd minute.

Throughout the game Ronaldo and Mikael Lustig went head to head, with the Swede aquitting himself well against one of the World's best. 

This however, wasn't his finest moment.
