Chelsea look like a team without a weakness after winning an 11th successive Premier League game, according to Match of the Day analyst Danny Murphy.
Diego Costa scored as the leaders won 1-0 at Crystal Palace on Saturday to move nine points clear at the top.
"I can't see one area in their team where they're struggling at the moment," Murphy said.
"It's fantastic for Chelsea supporters and worrying for everyone else."
Chelsea's lead will be reduced by the end of the weekend, with third-placed Arsenal visiting Manchester City, in fourth, on Sunday and second-placed Liverpool contesting the Merseyside derby on Monday.
