New Wigan boss Steve Bruce was unable to hide his frustration at the way a financial dispute with former club Birmingham became public knowledge.
Bruce managed Wigan for seven weeks in 2001
The row over image rights, which has been resolved by Bruce repaying some money to Birmingham, delayed Bruce's arrival at the JJB Stadium by a week.
"It has left a bad taste in the mouth after six years of decent service to the football club.
"Things in contracts should, I believe, remain private," said Bruce.
"It was unfortunate it was addressed in the media. It left me in an embarrassing situation and one I'm very disappointed with.
"I think familiarity breeds contempt.
"Having been here six years and having certain promises taken away, like new contracts, it was disappointing."
Wigan have lost their last eight Premier League games and lie second from bottom in the Premier League but Bruce is confident the club can retain their top-flight status.
"It will be difficult," said Bruce, as the 46-year-old was formally unveiled as Wigan manager.
"I'm confident I can do the job and keep them in the Premier League."
