Here's further proof that Diego Costa has always been pretty physical on the football pitch.

This footage from a game between Braga and Benfica – taken from when Costa was playing in Portugal – shows that the Chelsea striker's stamp on Liverpool's Emre Can this week wasn't the first time the offence has been committed. 

Emre Can and Martin Skrtel received the Costa treatment this week.

This attack from 2007 only received a yellow card – no wonder he's still doing it.
