5 things we learned from Chelsea v Southampton

Back with a brace

Diego Costa returned to his scoring ways on Tuesday night, having not scored in his previous seven games for the Blues.

Costa’s first goal was a fantastic header from a smartly taken corner. That was his 50th Premier League goal, making him only the seventh Chelsea player to have reached that feat.

Soon after the goal, Costa’s confidence shot back up, the home fans that were singing his name encouraged him to go and get his second of the match.

He combined with Eden Hazard and Pedro in a move which saw him both a start and finish a superb Chelsea move.

The 28-year-old Spaniard was named man of the match after grabbing two goals and providing the first goal, when he set up Belgian team-mate Hazard.

Costa has regained form at the best possible time as Chelsea go into their last six games in all competitions in the hunt for the league and FA Cup double.
