David Sullivan has given his backing to Birmingham owner Carson Yeung as he prepares to return with West Ham for the first time since leaving St Andrew's last season.
Sullivan and co-owner David Gold sold the West Midlands club to Hong Kong businessman Yeung for £81.5million after 16 years in charge. A bitter war of words and a High Court battle followed. But Sullivan is adamant that is all in the past and believes Yeung and his right-hand man, Peter Pannu, have done a good job at City.
Sullivan told the Birmingham Mail: "I hate confrontation and things have now run their course and there are no problems. Peter Pannu was doing his best for Carson Yeung and I respect him for that. In fact, I have huge respect for Carson and Peter."
He added: "It was business, one professional against another. Nothing really bad was said and, from the bottom of my heart, I have admiration for them.
"Peter has done a marvellous job. You have to say 'well done to them'."
Sullivan added: "When we sold Birmingham, we sold to someone we felt had the club's best interests at heart.
"What Carson Yeung has done so far, he deserves credit for that.
"The team had an exceptional season, he invested money on players and has not put Birmingham City at risk.
"The spine of a good team was there and Carson has spent money on it and improved it yet again.
"He seems to have a long-term plan and, to those people who are wary because he's Chinese and there's still some mystery, I would say when we took over, we were outsiders and no one knew us."
