MLB.com has some quotes from Posada on the subject of Bernie. A sampling:

Posada said that he has spoken "a lot" with Williams this offseason about the 38-year-old outfielder's future. The Yankees appear to be set with four outfielders -- Hideki Matsui, Johnny Damon, Bobby Abreu and Melky Cabrera -- but Posada said that Williams is hungry for one more season.

"Obviously, he wants to come back, and he wants to come back for the right reasons," Posada said. "If he doesn't come back as a Yankee, it would be tough to see him in another uniform. I don't think he would even consider that."

Williams told Posada that other clubs have called with offers but that he has his heart set on the Yankees.
