"Amidst rumours of a £25 million move to Everton, he signed a new four-year deal on 2 August 2016" -Wikipedia.
Still though, if Swansea go down he wont be happy being held hostage for an extortionate fee. I'd be happy with £20m or so,
otherwise leave it.
I'd love him here. Work horse, great technique, scores goals, assists, awesome deal ball expert. Plus he wouldn't cost a bomb in wages.
