Southampton 1 Chelsea 4
Chelsea produced a clinical display to see off Southampton and secure back-to-back Premier League wins.
Academy graduates Tammy Abraham and Mason Mount scored within eight minutes of each other before Danny Ings pulled one back right on the half-hour mark.
The Blues, who were in full control of proceedings, looked shaky after the Saints’ goal but N’Golo Kante restored their two-goal cushion with a deflected strike shortly before the break.
Despite an impressive first 45 minutes, Chelsea were fortunate Southampton did not punish their defensive mistakes on several occasions.
After the Saints failed to capitalise on Kepa Arrizabalaga’s poor clearance, Jorginho prevented a certain goal by denying Ings after Fikayo Tomori was dispossessed near his own goal.
Chelsea had a chance to extend their lead early into the second half when Callum Hudson-Odoi was thwarted by keeper Angus Gunn at close range.
Although Southampton tried to muster a comeback, going close through a James Ward-Prowse free-kick, the Blues made sure of the points a minute before full-time.
Lampard’s substitutes made a near-instant impact when Christian Pulisic and Michy Batshuayi combined for the fourth, with Batshuayi finishing coolly.
Chelsea have now secured three successive league wins away from home for the first time since December 2018.
Subs not used: Caballero, Christensen, Barkley, James.
