The sad reality is that Rafa's true rank would be outside top 100 right now and that is being generous.
I am afraid the fall is too steep.
It would take 8 months just to fix fitness.
And then there is his game. Nothing can fix it unless he starts practicing 7-8 hours a day on clay.
He should be on clay right now. Practicing.
He does not need a coach. He needs his fire and hunger and drive back.
