Chelsea went ahead on the half-hour when Ross Barkley, who was recalled to the England squad midweek, did well to win possession in midfield and set up the unmarked Hazard to fire the ball past Alex McCarthy for his seventh league goal of the season.

Barkley scored one and made one for Chelsea.
Willian (6): he didn't put in much effort, he lost some passes but still manage to put through some passes that ended up as goals.
The Blues remained in the ascendancy with Barkley curling over the crossbar but after being second best during the opening quarter, Southampton finally offered a positive response. The Belgium worldwide was a constant torment to Southampton's backline who had no real answer to his creativity, pace and world-class skill. Held the ball up well and was unlucky not to win a penalty in the first half when it looked like he had been brought down by Wesley Hoedt. The Netherlands global escaped punishment for his challenge on Giroud in the area but then saw Hazard capitalise on some lazy defending as he stepped out of defence and left Chelsea's main man all alone. Provided an acrobatic assist for Barkley to tap in Chelsea's second.More news: Hamilton wins F1 race in Japan, challenger Vettel sixth
