The 31-year old striker has signed a three-year deal with Birmingham City after spending last term at Ricoh Arena and has been slammed by Sky Blues chairman Ken Dulieu for 'betraying' the club.
But King has defended his decision to depart Coventry, saying they did not give him the three-year deal that had been agreed upon.
"I am looking forward to a new chapter in my life and getting on with the season," he told Sky Sports News.
"I didn't turn my back on anybody. You would have to ask them that question. I verbally agreed a three-year contract, not a two-year contract.
"I don't want to get into a slanging match with people that gave me an opportunity to resurrect my career.
"I just want to wish them all the best and thank them for all that their support.
"I never lied to them and said I would be staying. Everything had to be right, and it wasn't.
"I am a Birmingham City player now and I am looking forward to playing for them."
