So, you think it's worth paying him, despite the fact he, in your words, has decided against actually working for us, and has decided to prepare for another challenge? You think that's reasonable.
Other player's worth is for other player's threads. That's not the argument here.
No, I don't think he's worth what we pay him. We pay him like one of the best in the world. Does he consistently give us that? Not in my opinion. And right now, when he's preparing for another challenge? Then he's definitely not worth it. He has a contract. I very much doubt the contract says "You must play, unless you don't really feel like it because we're not in the runniing for the league title or CL trophy".
