Chelsea's narrow 1-0 win over Bolton at Stamford Bridge on Tuesday night has prompted manager Carlo Ancelotti to urged his players to remain calm.

The Blues opened up a four-point gap on Manchester United thanks to a 43rd minute Nicolas Anelka goal and now seemingly has the Premiership in their grasp with just four matches remaining.

Ancelotti said it was now time to focus and remain calm on the job at hand and praised his players for handling the pressure well.

"Now the Premier League is in our hands and we have to stay focused and calm," said Ancelotti.

"We have to play game by game, and we are not interested in the results of the other teams.

"There was pressure on us to get this result because we needed to improve our position, but I think the players now have very good motivation to finish the season well.

"It was not an easy game. We knew it wouldn't be, because Bolton came to Stamford Bridge to play their game. They put pressure for all the 90 minutes, a lot of long balls.

"It was a tough game for us, but I think that Chelsea did a good job and won, which was the most important thing. We were unlucky not to improve the scoreline at the start of the second half, but we needed the three points.

"We had 21 shots, so we deserved to win. There's no debate about this. It was difficult because, when you're 1-0 up, you have to be careful right to the end. For me, it was a very good performance."
