The Hoops are on the verge of securing their 44th Scottish title and have subsequently had their fair share of positive contributors throughout the campaign.
But Provan feels that Kenyan powerhouse midfielder Wanyama has been the most vital among all of Neil Lennon's men.
"So who were the main men for the champions?" was the question posed by Provan in his column for SunSport.
"In the absence of Anthony Stokes, Hooper's 16-goal SPL contribution has once again made the difference.
"Kelvin Wilson has had a terrific season and could claim to be the most improved player at the club.
"For me though, Victor Wanyama has been the main man.
"It's hard to believe the Kenyan midfielder is still only 21 and will only get better. He looks like a man amongst boys in the SPL.
"With Hooper and Wanyama likely to leave in the summer Lennon has to keep the rest of the squad intact, but that won't be easy."
