Branislav Ivanovic headed in a late winner for Chelsea as they claimed a come-from-behind 2-1 victory at Southampton, whose mammoth run without conceding finally came to an end.
Ronald Koeman’s men went into Saturday’s match at St Mary’s Stadium on a run of six league games unbeaten and six consecutive clean sheets.
They looked solid for much of the encounter with Guus Hiddink’s rejuvenated Chelsea, with goalkeeper Fraser Forster reaching 667 minutes of top-flight football without conceding to set a new club record.
Shane Long then opened the scoring courtesy of a defensive error at the other end, taking full advantage of a poor header from Chelsea left-back Baba Rahman with a 42nd-minute strike that looked like it would prove decisive.
However, Southampton’s backline fell asleep in the 75th minute, allowing Cesc Fabregas to level as Forster was beaten after 708 minutes with a cross-cum-shot.
