Fabregas does not think he or his team-mates should be talking up their chances, but admits the team are driven to succeed for injured colleagues like Aaron Ramsey, Robin van Persie, Kieran Gibbs and Johan Djourou.
"The Aaron thing, Robin, Gibbs, Johan Djourou, they made us more united," he said.
"We haven't seen Robin for four months, we don't know anything about him but Gibbsy and Johan we see them all the time and they would love to be in our position, so that is making us more united as a team.
"Hopefully we can do it for the club, for the fans and also for them.
"We have never talked (about the title), we just kept going and going. But now even more it is the time to be doing our talking on the pitch because we have a great opportunity."
