Dolly left Mamelodi Sundowns in the January transfer period to sign for French Ligue 1 side Montpellier following his impressive season with Sundowns, which culminated in him helping the Brazilians lift the 2016 CAF Champions League trophy.
The former Ajax Cape Town midfielder also started a similar footballing path as Buckley by captaining the South Africa Under-23 side in last year's Olympic Games, the same role held by the latter at the 2000 Games in Sydney.
And former Borussia Dortmund midfielder Buckley believes Dolly can reach the very top level in European football.
“Wherever I go, everyone tells me ‘Keagan Dolly is just like you 'Bucks', just like you, same mentality, and skills, same speed’,” Buckley said at his book launch at Moses Mabhida Stadium today.
"Same left footer and some resemblance [he laughs]. He can reach the highest level and he has shown that at Sundowns and but he just needs to show it in Europe and I’m sure he will.
"He has all the skills, speed and a dangerous left foot and I'm sure he'll make us proud."
Buckley, who is the assistant coach of National First Division side AmaZulu, had some further words of advice for Dolly.
“[Dolly should] maybe take more responsibility in the game when he gets the ball and don't be scared on taking on players and that is what I used to do," he reveals.
"Whenever I used to play, if 'Bhele' Siyabonga Nomvethe couldn't get the ball from the back, I had one thing in mind; play in front of me I'm going to take him [my marker] on and I don't give a damn who it is, I'll go passed him, and that is what he wants to do.
"He must do more of that and I'm sure people in South Africa want to see more of him taking on, more going forward and more putting crosses; not always getting the ball and playing it at the back, simple.
"Anyone can do that [play the ball backward], any footballer, even my daughters can do it at home. But he must get the ball and take [players] on and take his chances."
