Having signed James Rodriguez from Real Madrid, the Toffees continue to strengthen their midfield by bringing in yet another rated midfielder Abduolaye Doucoure from Watford.
The French midfielder has signed a three-year deal worthy £20 million plus add-ons.
Doucoure, 27, spent four years playing for Watford prior to relegation from the Premier League last season.
He is set to continue his career in the English top flight having penned a three-year deal to join Carlo Ancelotti’s squad.
Doucoure made 39 appearances and scored four goals for Watford last season, having scored 17 goals in 141 games during his time with the club.
“I have been waiting a long time to come here and now it has happened so I am very happy,” Doucoure explained according to Goal.come.
“I had some interest from other clubs but from the beginning when Everton showed an interest in me I told my agent to focus on Everton.
“It was the only club I wanted to join.
“Everton has a big history in English football and it is a good club for me to have a step up in my career.
“I am very happy now to be an Everton player and very excited for the future. I can bring my energy – I am a powerful player, I can run a lot, all the game.
“I can add goals as well. I will try my best to score goals and help the team.
“It is an ambitious project here and it was a big part of my decision, having [Director of Football] Marcel [Brands] and the coach Carlo Ancelotti wanting me.
“When you come to a club you want the manager and, of course, the Board to support you.
“It was the case with Everton and I was very eager to come here.”
