Shaquille O'Neal has been trying to convince the Celtics to sign him in order to make another run at an NBA championship.

Two sources close to O'Neal confirmed his interest in signing with Boston. There have been reports that O'Neal, an unrestricted free agent, is asking for too much money and too big of a role at this point in his career.

Unless the Celtics were to work a sign-and-trade with the Cavaliers, they can only offer him the veteran's minimum of $1.35 million.

"He only wants to go to a team with a chance to win it all," one source said. "That's a short list. Even for the money, he's not going to a non-contender."
