Speaking on Go Radio, he said: "I personally think he'll stay another season or two.
"He won the league this season and has a real opportunity of winning the Double, they're in the Scottish Cup quarter-finals.
"They've still got to be respectful, they've still got St Johnstone and then obviously the semi-final and final.
"I think he knows he needs to get a few trophies in the bag, get that experience of winning as a manager.
"Then I think his time will come, there's no doubt. He's impressed me as a manager, he's got better every season.
"The way he comes across in the media I think is first class, very honest when he gets interviewed.
"So for me he stays another couple of seasons."
"The reason why I think he'll stay is he's got a Champions League opportunity, that's the elite of football for me.
