N'Zogbia finally elected to join Alex McLeish's side this August after spurning a chance to sign for the Scot at Birmingham City a year earlier.
"I nearly signed for Birmingham and Alex, but I didn't agree personal terms," he explained. "Sometimes it happens. If you are not happy with the contract, no one is forcing you to sign it."
He said: "It is really good to be here. I know from training we have some really good players. It will take time but I think we will be a good team and hard to beat.
"We lost two great players and now have to deal with a lot of young players."
