Murray and Nadal after the Scotsman won an easy Madrid final.(Getty Images)

Andy Murray is unbeaten this year on clay, including a win over Rafael Nadal in the finals of Madrid. It’s a surprising result for a player who usually reacts to clay about as well as an August sun. But Murray has no illusions about his recent clay success, as evidenced by this great Twitter exchange between the heavily-followed BBC Sport account and his own.

I guess that settles it. Rafa is the king until otherwise noted.
