Birmingham manager Harry Redknapp has told Sky Sports he would be interested in signing Ashley Cole, Stewart Downing and Robbie Keane if they are available.
The former Tottenham, West Ham and QPR manager saved Birmingham from relegation and hopes to challenge for at least a place in the top six ahead of his first full season in charge.
"Ashley Cole, for me, was the best left-back in the world a few years ago. He was just a fantastic player," Redknapp said.
"He's out in America. I don't know what Ashley's plans are. His name was mentioned to me.
