Mason Mount and Timo Werner both scored twice while there were also goals for Marcos Alonso and Kai Havertz for Chelsea at St. Mary’s Stadium. Southampton have been beaten 9-0 in each of the past two seasons and a similar scoreline looked likely when Mount scored Chelsea’s sixth goal in the 54th minute. The visitors stepped off the pace in the final half-hour, though, perhaps saving some energy before the second leg of their Champions League quarterfinal matchup against Real Madrid on Tuesday. Madrid won the first leg 3-1 at Stamford Bridge and Thomas Tuchel took the opportunity to withdraw Havertz, Thiago Silva and Mount early. It could easily have been a heavier loss for Southampton, with Werner striking the goal frame on three occasions in the first half. Chelsea consolidated third place in the league and moved 10 points behind second-place Liverpool.
