David Gold has taken a new swipe at Birmingham City owner Carsen Yeung.

Gold, his brother Ralph and David Sullivan sold their Birmingham shareholding when Hong Kong tycoon Yeung completed an £81million takeover last month.

But the changeover period has descended into bitterness with the police and fraud squad due at St Andrews today to probe Premier League City's books.

Gold told the Mirror: "They have spent a huge sum of money so they are entitled to do what they like but football is a very small family, and what goes around comes around.

"Maybe these people hold grudges longer than most.

"They are really going to need to learn quickly, otherwise they are going to make a lot of enemies.

"What football knows of us is that for 16 years we have run an extremely tight ship under difficult circumstances, we took a club from the third division to the Premier League.

"And that club has remained fairly solvent throughout our tenure, while around us clubs have been collapsing."
