Romelu Lukaku marked his return to Stamford Bridge with a goal as Chelsea beat Aston Villa 2-0.
Lukaku struck in the 15th minute when latched on to Mateo Kovacic’s superb through-ball, before firing beyond Jed Steer for his second goal in three matches.
Aston Villa responded well and forced Edouard Mendy into a brilliant double, as he denied Tyrone Mings and Ezri Konsa.
Kovacic doubled Chelsea’s lead on 49 minutes, capitalising on a mistake from Mings before lifting the ball into the far corner.
Marcos Alosno came close to adding a third, but his shot went just wide of the right post.
Chelsea return to second, level on 10 points with Manchester United, while Villa drop to 12th on four points.
