After striker Georgios Samaras took the armband for the Hoops' final pre-season tour match of Australia against Melbourne Victory on Wednesday, Commons said that the Greece international just wasn't quite up to the standards of the Scotland midfielder.
"He is a role model and a leader - a natural born leader," the former Derby County man said.
"He is a natural captain. He certainly gives a better speech in the huddle than Georgios Samaras!
"He is one of the best captains I've been under. He has the respect of the whole changing room."
