Chelsea captain John Terry insists the title is not yet won after victory over Manchester United.
Jose Mourinho's side moved 10 points clear at the top of the table after Eden Hazard's goal was enough to beat Manchester United.
When asked if the title was already in the bag, the Blues skipper was steadfast.
"No, I don't think so," he told Sky Sports 1. "It was a massive win. We needed to win. It was a really tough game but we got the three points.
"They had the better possession. We have not been playing as well as we can of late and we done that today.
"I think we are doing enough, we have done all season. We were in our best form early on in the season and just before Christmas.
"We are still getting results and that's the mark of champions."
