Southampton secured their first clean sheet in 11 Premier League games as Ralph Hasenhuttl’s side produced a battling performance to frustrate Chelsea and secure a point at Stamford Bridge.
The Blues, fourth in the Premier League, had more than 70% possession but could not break down a well-organised and disciplined Saints side.
Chelsea’s best chance fell to Eden Hazard, but his well-hit shot was saved by Premier League debutant Angus Gunn.
Alvaro Morata thought he had scored when he put the ball into the net midway through the second half, but it was ruled out as he was given offside
Southampton offered little as an attacking force, with one Oriol Romeu shot easily saved by Kepa Arrizabalaga.
