Keane said: "Football is a small world and you hear things through the grapevine.
"I just got the impression that Leighton had his heart set on a move to Everton.
I don't blame him for that." Keane added: "When I left Manchester United, it didn't matter which team came in for me I was always going to go to Celtic.
"I met Leighton and he's a nice lad who I would have loved to have come here. But it didn't happen and we move on."
Yes, please move on Keane.
