Chelsea beat QPR 1-0 at Loftus Road and Jose Mourinho said the Blues have taken an important step towards the Premier League title.
Cesc Fabregas secured a late goal in the London derby as Mourinho's side moved seven points clear off Arsenal who sit in second place.
However, the Portuguese boss heaped praise on his side who controlled the game and registered another clean sheet on Sunday.
"The title is one step closer," he told Sky Sports. "We need three victories and two draws so our situation is good. Championships are pure mathematics.
"It's one less match that we need to win so it's a very important step after a very difficult match.
"Our best quality was to control the game very well and to stop our opponents scoring. They are a team who can score goals, they have dangerous attacking players.
"They play dangerously, direct and objective for the two strikers so it that was our best quality. We kept calm and tried to play against a team who were very well organised defensively, they did fantastic work to keep the clean sheet.
"Throughout the season, you have these moments where you lose points at the end of the game. Today we won two points in the last two minutes."
Mourinho also hailed Chris Ramsey's side who are well involved in the relegation battle.
"It was always going to be difficult to score goals here so it was important for us to keep a clean sheet," he added
"We didn't have any strikers on the bench to try and change to a different shape like we normally do so to keep a good balance tactically and emotionally was very important.
"Both teams managed to compete at a high level, but in a clean way without losing control of their emotions.
"In the end, there was a star that shined for the teams who are going to be champions."
