This. I'm not his biggest fan and I think he's nowhere near as good as made out, he is undoubtedly box office... If we got him at the quoted astronomically absurd price+wages, he'd be prohibitively expensive... Even for Real and even for free in a post-Brexit world.
If he leaves after 4 years, the potential return on the investment in terms of trophies won and money made in marketing terms, it would have paid for itself. If, in the unlikely event he left after two years, he would cost an even bigger amount.
No matter which way you look at it, it's win-win.
