Former Chelsea star Joe Cole believes Frank Lampard's team can make a Premier League challenge this season.
Cole was speaking after their 3-0 win at Burnley.
"It was an exceptional performance and it's been a steady improvement," Cole said on BT Sport.
"Now it looks like Chelsea can make a run of it. It's been a long time since Chelsea have looked as comfortable defending. Mendy didn't have a shot to save.
"It's good times for the club at the moment and it's just about consistency. You look at the fixture list and there's winnable games to come.
"By Christmas time Chelsea could be right up there. It's game on.
"I think there are three or four clubs who can go for the title and Chelsea are certainly one of them."
