Multiple sources have told Yahoo! Sports that the Celtics are looking to trade Ray Allen for a younger, cheaper guard with an expiring contract.

In doing so, Boston would be able to find a replacement for Allen, 34, without losing him and his $20 million expiring contract for nothing this summer.

Celtics president Danny Ainge will have a difficult decision to make because there really isn't a guard available that is currently at Allen's level.

Allen has expressed his desire to re-sign with the Celtics this offseason, but has also acknowledged the fact that the interest may not be mutual.

The only team that is showing interest are the chicago bulls.
