(Reuters) - Arsenal's clash against London rivals Chelsea is the north London side's last chance to stop the Premier League leaders from running away with the title, former France winger Robert Pires has said.
Arsenal, in third, failed to capitalise on Chelsea's draw at Liverpool as they lost at home to Watford on Tuesday and will go 12 points behind the table-toppers if they are beaten at Stamford Bridge.
