Antonio Conte has criticised his Chelsea players for failing to take their chances against Swansea City, but admits that picking up a 1-0 win is all that matters.
The Blues dominated first-half proceedings in South Wales and took a deserved lead into the break through Cesc Fabregas's fourth-minute curler, which they were unable to add to.
Swansea almost capitalised on Chelsea's profligacy with a couple of late chances, though in the end Fabregas's first league goal since August proved the difference between the sides.
After closing to within two points of Tottenham Hotspur, who play their game in hand at home to Watford on Monday, Conte is glad to have turned up the heat on the Lilywhites in the race for a top-four finish.
"We started the game very well and dominated the game in the first half. But you must be very good to kill the game and you have to take the chances otherwise you risk your opponent trying to push," he told BBC Sport. "We were very good defensively and it's important for us to take three points with a good win.
"Now we have three games to go and have to win for our fans, for our work and then we'll see what happens. The big problem that we are having this season in many games is that we create many chances to score but we don't take them.
"If we want to fight for something important you must be clinical. If you don't kill the game then it's normal for the other team to push. Our expectation was to play a tough game against a good team looking to avoid relegation.
"They only way that we have to put a bit of pressure on the top four is to win. Today has been very positive to put that pressure on Tottenham. Football is not simple and anything can happen."
Chelsea return to action next weekend with a home match against third-placed Liverpool.
