Doucoure says Dyche is the ideal manager for Everton.
“We knew from last season that we needed to change something," he said.
“The manager understands us very well and has a lot of experience in the Premier League, so he has just given us confidence and belief.
“He was a big change for the club, and I would say that he is the perfect fit. The manager is very honest. He tells us the truth, no matter what, so he's been good.
“He has done a lot for me. I was not even in the team. When I signed my new contract, he joked with me and said, 'You are not even in the picture'.
“It was a good joke from him. It made me smile because I was happy. He believes in me, but he believes in everyone. He gives every player a chance to play."
