Gary Bowyer and Karl Robinson were once colleagues on the touchline together, but this Saturday they'll be rivals in opposing dugouts.
Rovers travel to stadiummk for the first time in a league encounter with Bowyer full of praise for the work Dons boss Robinson has done.
The former Rovers coach has been in charge at MK since May 2010 and has overseen their progression culminating in last season's promotion to the Championship.
"Karl is great, I think he has done a wonderful job there," said Bowyer.
"When he first took over at MK people were talking about how young he was, but he's done a fabulous job there playing a great brand of football.
"What he has done is he's put his stamp on it and the club reflects how he sees the game to be played and I think it is something that he has to be applauded for as there were always going to be doubters and knockers but he's not paid any attention to that.
"I don't think it will be long before he is managing even higher in my opinion."
Robinson, who joined Rovers as part of Paul Ince's backroom staff in the summer of 2008, looks back with fondness at his two years with the club.
"I know Blackburn very well because of the time I spent there," Robinson told mkdons.com.
"I've an affinity with the club and I will do forever because I loved my time there. It's a great part of the world and the fans are fantastic.
"The backroom staff at the time were great and I know Gary from that time as well."
