Southampton left Stamford Bridge with a well-earned point after holding depleted Chelsea to a 0-0 Premier League draw on Wednesday.
Chelsea produced a toothless display as they were held to a 0-0 draw at home by struggling Southampton and lost Willian to injury in the process.
Maurizio Sarri reinstated Alvaro Morata to the team with Olivier Giroud ruled out, yet the service to the Spaniard was poor as Saints dug deep to hold on for a well-earned point.
A tame first half passed with few flashpoints, though Chelsea did see Willian forced off on the same day the club announced the signing of Christian Pulisic, who will arrive at the end of the season.
