With the scores at 2-1, Diego Costa easily overcame Southampton full-back Ryan Bertrand to head a powerful one into the Southampton goal, much to the delight of the Chelsea fans.

Chelsea fans took to twitter to sarcastically thank the former Chelsea man who came through the ranks at Chelsea and even started in the Champions League finals against Bayern Munich.

Love how Bertrand let Costa score. Always a blue.

Another Fabregas assist. Y'all know Bertrand still has Chelsea at heart 😂
