Koeman said: “It’s really good for the club to have someone in Steve who has shown his quality in his job at a number of clubs over many years.

“That’s the experience and quality he will bring to us at a good time in the season. He has a great deal of knowledge about building for the long-term and the magnificent work he did at Leicester on top of the job he did at Chelsea makes us excited to have him here at Everton.”

It is believed Everton paid around £2 million in compensation to land Walsh, who has also worked at Chelsea and Hull City.
