The punchline here would be that he isn't trying to lure Lionel Messi to Chelsea, he is actually luring Lionel Messi to Chelsea. Like Yoda said, "do or do not; there is no try," right Cesc?
But there's no punchline. There's just annoyance from the Chelsea midfielder after the media have blown a few innocuous comments out of proportion. I doubt Fàbregas is surprised that they were blown up like that -- he's been around long enough in both England and Spain to know better, surely -- but it's probably still annoying to be quizzed on such things on a regular basis.
"I get a bad feeling about it when people are saying that I am trying to convince Messi to join Chelsea. What makes people think I can discuss contracts? I am just a footballer."
"Leo will do whatever makes him happy. As his friend and former team-mate, it would be great if I get the chance to play with him again."

And there you go again, Cesc! What did we just talk about!? Don't feed the trolls.
