He revealed that he turned down an approach from Chelsea to seal a switch to the Birmingham-based club.
The highly-rated 20-year-old, who played against Chelsea for FC Nordsjaelland in the Champions League last term, joined Paul Lambert’s side at the weekend for a fee believed to be in the region of €4.7 million.
And the centre-back has claimed the Europa League holders were also keen on securing his signature ahead of his move to Villa, but he is sure he made the correct choice.
“I have a good feeling it was the right decision to turn down Chelsea,” Okore said.
Okore says Lambert was a key influence on his decision to choose last season’s 15th-placed finishers in the Premier League, and is looking forward to progression in England’s top flight.
“I’ve got a good insight into Lambert and his plans,” Okore continued.
“He knows what I stand for, and he knows what I can do. He hopes that I am myself and play the football I want to play.
“He believes that I can develop as a footballer, and therefore it was easy to say yes to him.”
Okore, who was born in Ivory Coast, has been capped seven times by Denmark.
