Calderwood decided to leave Brighton for Villa to become the latest addition to Bruce's backroom team following his appointment at Villa Park more than a month ago.
But despite leaving a team who currently sit in the automatic promotion spots in the Championship, and a manager with whom he has worked with at four different clubs, for a side that is just one point closer to the top six than the bottom three, Calderwood insisted that returning to an old team was not the reason for his decision.
"It's been a difficult decision in the first place to leave Chris [Hughton] and Brighton, but I’m delighted to get the opportunity," he said, as reported by the Mail.

"It's not so much coming back, I was only here for a short period as a player. It's the size of the club and where I hope we are going to be able to get to which made it really exciting for me."
As the retired defender suggests, his affiliation with Villa is perhaps not strong enough to inspire the move that he has made on its own.

However, the fact that he has played for Villa - and come up against them on numerous occasions - during his playing days will surely mean that he has a good idea about what the club is about.
And having only previously been involved with the club while they were in the Premier League, he perhaps feels that they have a greater chance of establishing themselves at the highest level than Brighton do, despite their current positions in the second tier.
