Tammy Abraham moved to joint-top of the scoring charts as Chelsea rose to fifth in the table with a 4-1 win at Southampton.
The visitors to St Mary's took the lead on 17 minutes as Abraham was sent through by Callum Hudson-Odoi and lobbed in for his eighth goal of the season.
Seven minutes later Mason Mount doubled the lead, but Danny Ings halved the deficit on the half-hour, guiding in Yan Valery’s cross.
N’Golo Kante’s deflected shot restored Chelsea’s two-goal advantage before the break.
Angus Gunn denied Hudson-Odoi early in the second half but could not stop Michy Batshuayi adding a late fourth after he combined with fellow substitute Christian Pulisic.
Chelsea rise to fifth, on 14 points.
Southampton’s third consecutive defeat leaves them on seven points in 17th.
