Crystal Palace equalised late to leave Chelsea winless in four Premier League games -- and looking over their shoulder in the race for a Champions League spot -- as Jean-Philippe Mateta cancelled out Cole Palmer's first-half opener.
Chelsea had chances to seal victory before Mateta picked up a ball from Eberechi Eze in the 82nd minute and blasted home from close range to ease Palace's relegation worries.
Palmer had given the visitors a deserved lead in the 14th minute when he fired in an angled shot after fine work on the left by winger Jadon Sancho who dummied his marker on the halfway line to sprint free and set up the England forward.
