Chelsea skipper John Terry says their late season title tilt is down to "great" manager Carlo Ancelotti.
Chelsea can go top with victory at Manchester United this weekend.
Terry, who made his 500th Chelsea appearance against Tottenham, said: "We deserved that because we never give up and that's the mentality of the football club.
"We've got that mentality on the training pitch, a great manager the players believe in and trust. He deserves a great deal of credit.
"He took a lot of stick but he kept us going and, with the formation, went back to what worked for us earlier in the season. We will never give up."
