Sunderland boss Keane still surprised by Hughes management plunge
"Sparky's been a manager a lot longer than me and I respect what he's got to say.
"We talk about players, tactics, referees - whatever. The good managers don't try to hide anything. They're happy to give their advice.
"I didn't think, as a player, he would go on to become a great manager but he's doing great.
"The obvious ones were Steve Bruce and Bryan Robson.
"Sparky wasn't top of the list when it came to would-be managers. He was very quiet until he was out on the social scene!"
