Hughes was dismissed by City in December 2009 and was swiftly replaced by Roberto Mancini, but there is no lingering ill-feeling towards the club.
He told The Sentinel: "The longer time has gone on, I think they look back and realise I did a decent job.
"There was a change of ownership, which wasn't easy. Also, the circumstances when I went were different to what they were portrayed to me.
"I don't hold any resentment about that. The fact was I drew too many games and gave them the opportunity to go in a different direction.
"I think they would have done it sooner, but I didn't give them the opportunity because we won our first five games that season."
