It's a strange one. If it exists, it's obviously not in our interest to advertise it, but if Suarez's agent wants Real to know they can buy him for £40m and not a penny more, all he has to do is tell them. Doing it through the papers seems completely unnecessary. I can only think that the clause doesn't exist, but we want to anchor the £40m figure in fans' minds, so when he does go for £45-50m, we're all thinking what a great job Ayres/FSG have done, rather than "we've just finished 7th in the league and our best player's f***ed off to Madrid because we can't give him European football".
