Liverpool loanee, Takumi Minamino got on the scoresheet as Southampton hold Chelsea to a 1-1 draw, ending a six-game losing streak.
The Blues suffered a setback in their attempt to go a point behind Manchester United and Leicester City who have a game at hand and could drop out of the top four at the end of game week 25.
Minanmino put the Saints ahead in the 33rd minute after beating Ceasar Azpilicueta and Mendy by fooling them with a fake shot before sliding the ball into an open net.
Chelsea fought back in the second half and were rewarded with a penalty in the second half after Danny Ings fouled Mason Mount in the Saints box.
Mount stepped up to convert the spot-kick in the 54th minute as Chelsea pulled one back but the team failed to secure a comeback as they shared the spoils at the Saint Mary’s Stadium.
Jannik Vestergaard struck the bar, while Reece James blazed an effort over as neither side could produce the quality to find a winner.
