Diego Costa and Gabriel's clash at Stamford Bridge on Saturday resulted in the Arsenal defender being sent-off, but it wasn't the first time the pair have locked horns.
Costa's conduct in Chelsea's 2-0 win over the Gunners has been widely ridiculed, as he appeared to try his best to get the Brazilian defender dismissed.
However, the pair have a history, and clashed when Costa was at Atletico Madrid and Gabriel at Villarreal in 2013, with the roles somewhat reversed.
