David Sullivan made his feelings known about Carson Yeung's behaviour before Birmingham's victory over Wigan yesterday.
Yeung, who sat in the directors' box strategically behind owner, Sullivan, has upset the Birmingham chief by refusing to confirm an extended contract for Bruce despite it being offered by the board before it stood down.
How Yeung would have accepted such an aggressive stance will unfold over the next 24 hours, but it came nonetheless as a moral boost for Bruce who has been left quite shamefully uncertain about his future.
Bruce looked more relaxed than you would expect for a man who has been under so much pressure for so long.
He recognised Sullivan's support and said: "It was made for the sake of the club. We have to draw the line about where we are going to go in the future."
Sullivan has demanded a December deadline for the takeover and Bruce added: "Dave Sullivan has made all the big decision at this club for 14 years now, including six while I've been manager. He has never told me a lie. He shook my hand six months ago but things have been in abeyance since then.
"The club needs someone to take it forward to the next step - with or without me."
