Mark Hughes' success second time round at Manchester United convinced David Dunn to return to Blackburn Rovers last season.
After an injury-plagued time at Brum, Rovers snapped him up for a cut-price £2.2million in January.
Dunn said: "A lot of people say never go back to where you've been successful but I'm more mature now as a person and a player."
Sparky returned to Old Trafford in 1988 after two seasons at Barcelona and Bayern Munich and helped transform United from perennial also-rans to English football's dominant force.
Dunn added: "When I met the gaffer he just said 'Well I went back to United' and everyone knows what happened there.
"That changed my mind a little and I'm glad I made the move."
