The 33-year old left-back will depart Chelsea this summer and is on the hunt for a new club with some reports suggesting he will seek a move away from England out of respect for the Blues.
But Charlton Athletic legend Powell believes the ex-England international could be of great benefit to Premier League outfits United or Liverpool if either club wanted to go after an experienced defender.
"But he could easily fit into those clubs no problem. He is absolutely capable of doing a job in the Premier League for the next two or three years.
"I think he will be a player much sought after and whoever gets him will be a very fortunate football club and a very lucky manager because they are going to have a very good player."
