Chelsea boss Frank Lampard says they won't get carried away after victory over Leeds sent them top of the table.
Chelsea are a point clear, though have played a game more than Tottenham and Liverpool.
Lampard said, "It's early December and there's a long way to go. But we are a progression. When you bring in new players, have young players and you're trying to integrate... Whether it's this season we get to the heights we want, I don't know.
"But we are moving in the right direction. I'm really pleased. It's work on the training ground and staff behind the scenes. At our level, at Chelsea, people will always question us. Our job is to not get caught up in the chat. We have to keep our feet on the ground. There's a long, long way to go. At the minute we're in a patch."
