Chelsea needed a stoppage time penalty to salvage a point against West Bromwich Albion at Stamford Bridge on Saturday afternoon.
Samuel Eto’o opened the scoring on the stroke of half-time with his third goal in two games, only for Shane Long to level terms on the hour mark.
Stephane Sessegnon then put the visitors in front eight minutes later, though just when it looked like Jose Mourinho was going to suffer his first ever league defeat at Stamford Bridge, the hosts were awarded a penalty in the fourth and final minute of stoppage time.
Eden Hazard, who was recalled to the Chelsea starting XI after being dropped in midweek, dispatched the spot-kick to give the Blues a share of the spoils.
Home wins for Liverpool and Southampton over Fulham and Hull City respectively saw them both leap frog Chelsea, who drop to fourth place ahead of a visit to West Ham United a week on Saturday.
Meanwhile, Premier League leaders Arsenal will reignite their interest in Demba Ba with a £15m bid when the transfer window reopens in January, according to the Daily Star.
The Gunners were close to securing a last minute loan for the Senegal international on loan in the summer, on for Mourinho to pull the plug on the deal.
