Antonio Conte has set Chelsea a 29-point target for the Premier League title after victory over Swansea saw them go 11 clear.
Goals from Cesc Fabregas, Pedro and Diego Costa secured a 3-1 win at Stamford Bridge after Fernando Llorente's headed equaliser had squared the game before half-time.
Chelsea have won 12 in a row at home and the pressure is now on Tottenham to narrow the gap at the top when they play on Sunday, but Conte was customarily conservative after the game.
The Italian refused to acknowledge the legitimacy of his side's huge lead with all their rivals a game behind, while his 92-point title target assumes nearest challengers Manchester City will drop just two points in their remaining 13 games.
He told Sky Sports: "Eleven points is not really 11 points because the other teams have to play. We need another 29 points to win the league and if we are able to take 29 points for sure we will win the title.
"But 29 points are a lot, and there are 12 games until the end. It's important to go step by step, to continue to work and have the commitment of the players."
Swansea were obdurate opponents and had a shout for a penalty at 1-1 when the ball struck Cesar Azpilicueta's arm in Chelsea's penalty box.
Conte said Azpilicueta "was very close" to the ball when the incident occurred and felt his side were worthy winners against visitors who won at Liverpool last month and recently ran City close at the Etihad.
He said: "It's another step and a good win because for sure it wasn't easy to play against them. I watched their games against Liverpool and Manchester City and they played very well.
"Today we deserve to win the game, and we created many chances. It's a pity about the goal we conceded but in the second half we started again.
"We deserved a lot to win this game and I'm very happy for my players."
