Jorginho scored two penalties as Chelsea fought back from a goal down to beat Aston Villa and move level on points with second-placed Liverpool.
Villa had taken a fortunate lead in the 28th minute when Matt Targett's whipped cross from the left was met by Chelsea defender Reece James and his glancing header diverted the ball past Edouard Mendy and into the net for an own goal.
But Chelsea were level six minutes later with Jorginho converting a penalty after Callum Hudson-Odoi had been brought down by Matty Cash's clumsy challenge in the 18-yard box.
Substitute Romelu Lukaku, who had missed three matches because of Covid-19, came on at the start of the second half and scored within 11 minutes, heading in from Hudson-Odoi's cross.
