PREMIER LEAGUE: Chelsea do enough to collect point from Arsenal
Blues boss Roberto di Matteo made as many changes as realistically possible.
Di Matteo's much-changed team more than held their own but enjoyed another double dose of luck after Wednesday's Champions League win over Barcelona when Robin van Persie and Laurent Koscielny went within inches of scoring.
The Gunners now appear safe for third place, sitting six points clear of Spurs.
There was concern for Arsenal - and England - when Walcott pulled up with a hamstring strain and, although he briefly continued, he had to be replaced by Gervinho on the hour mark.
