Fellaini himself came out a few months ago and said he doesnt have a release clause.

I have heard about Chelsea monitoring me, but I have never spoken with them,’ Fellaini told Belgian media outlet sportwereld.be. ‘Throughout my time at Everton, there has been word on the grapevine of interest from some of England’s top teams, but I have never personally sat round the table with any of them.
If Chelsea want me, they need to come up with something, but they have not done so far. For now, I am very happy with Everton. We are fifth, and if we can climb just one more place, and stay there, we can look forward to playing in the Champions’ League. Would that make me stay? Maybe yes, because Everton are the team who brought me to England. I have a very good relationship with the manager and my team-mates, and the club are like my family.
‘People are talking about Chelsea as if I have already signed, but I am an Everton player, and maybe I will finish the three years left on my contract. If I do end up leaving, it would be up to the club to decide on the price.
I have all sorts of clauses in my contract, but there is no fixed fee for releasing me.
‘The Premier League is the best in the world, but I don’t have a dream team I want to go to. If I do leave Everton, it would be to a club who really want me and a manager who has really good plans for me. People seem to think that Eden Hazard’s presence at Chelsea might tip it their way. He is a very good friend, but so too are Mousa Dembele and Christian Benteke, so that wouldn’t influence anything.’
