Southampton was thumped 6-0 by Chelsea in the Premier League on Saturday, adding to a trio of lopsided scorelines over the last three seasons.
Timo Werner hit the post and crossbar before Mason Mount connected with Marcus Alonso to make it 1-0 in the eighth minute.
Mount turned from provider to goalscorer to double the lead on 16 minutes.
Werner would complete hitting all three posts before finding his own goal to make it 3-0 to Chelsea on 21 minutes. James Ward-Prowse’s header back towards his own half put Jan Bednarek into trouble, which allowed the forward to race onto the ball before rounding the goalkeeper to slot into an empty net.
Kai Kavertz scored to bring Chelsea’s advantage out to 4-0 shortly after the half hour mark with a simple a tap-in goal after Fraser Forster denied N’Golo Kante.
Werner doubled his tally four minutes after the restart before Mount added a second of his own.
Southampton has now lost four out of the last five games, including back to back home defeats.
