Southampton completed a stunning first-half turnaround to inflict Chelsea’s second defeat of the season with a deserved 2-1 victory.

Raheem Sterling netted his third goal of the season from close range in the 23^rd minute but the Saints bravely fought back through talented teenager Romeo Lavia, who blasted home from the edge of the area five minutes after to lift a subdued St Mary’s.

Southampton never looked back from there with Adam Armstrong firing home the winner in the added time of the first half to leave Ralph Hasenhuttl’s side above the Blues.

Thomas Tuchel’s side is now five points behind leaders Arsenal having taken only seven points from their first five matches despite their evening on the south coast starting perfectly.
