Juventus have apparently offered £19million for the Belgian, who is reportedly keen to leave Russia this summer. The 27-year-old joined the club in 2012, but is now looking for a new adventure.
The Serie A champions are keen on the midfielder, who could fill the gap left by Paul Pogba, should the Frenchman finally join Manchester United. It has been the story of the summer, yet a deal has still not officially been completed.
The news will come as a blow to Ronald Koeman, who was looking to add Witsel to his newly inherited Everton squad, as he prepares for his first season in charge at Goodison Park.
The Dutchman has only made two signings so far this summer, but is closing in on adding Ashley Williams from Swansea City.
The new season starts in less than 2 weeks, with Everton kicking off their campaign at home to Spurson August 13th.
