Wigan Athletic boss Steve Bruce will blank Birmingham City owners David Gold and David Sullivan at today's match.
He revealed: "I haven't had any contact with anybody since I left.
"Will I greet them? No. It's done and that's it. I'm totally disappointed with the way it ended, but there you go.
"It's amazing that greed was put before any friendships that I had made during my eight years at Birmingham as a player and a manager."
Bruce added: "People associate me with Manchester United, but my time as a manager and a player at Birmingham was almost as long.
"I signed 95 per cent of the players who will be in their squad. The way it ended showed a complete and utter lack of respect.
"That is the sad thing for me. After six years as manager, I thought I would have commanded a bit more respect than the way I was treated."
