Tottenham boss Redknapp: Celtic move stuff of dreams for Keane
Redknapp says the move will be a dream come true for Keane.
"He's the perfect player for them, he really is. It's a massive signing for Celtic. I've got so much time for Robbie as a player and a person. Robbie just wants to play all the time. He isn't happy when he's not playing.
"I didn't know about their interest until about 5pm when my chairman called me to say Celtic had asked about Robbie. It's all happened so quickly.
"But Robbie's a fantastic player and a great character. He's a great trainer. It's unfortunate, though, for Robbie that I've got a lot of quality strikers. We're very strong in that department.
"I've got Defoe and Crouch who have done well, plus Roman Pavlyuchenko who hasn't moved in the window.
"Now I've also got Eidur Gudjohnsen.
"Robbie's desperate to play every week and I think he's a big Celtic fan. It will be a great deal for them.
"Robbie goes to Celtic with my best wishes."
