If he goes to Inter, I think he'll put up good numbers. But he looks physically knackered. He was never a quick player, but he's struggling getting to balls slightly overhit, and the power in his legs seems to be gone with more and more weak shots.
This declining form started ahead of the '18 WC. I always thought it had something to do with him becoming a farther for the first time, and not using as much time on self-training as he used to do. Now I just think he's used up. Inter will get a brilliant player, but he'll never regain former strength
