I don't know actually which is my best surface, but like I said for me clay is the surface where there is real tennis. Where you have to be physically fit, where you have to be smart, how to play, where to play. On clay it not really happens some lucky things that can happen on hardcourt that the guy serves so good one game and then he makes one return out of nowhere, a winner on an important moment. On clay normally it's not going to happen, so on clay you have to be really fit to play each point, to play in the right directions, and you need to go and really get the guys.
Andrey Rublev looked ahead to the ATP 1000 Madrid Open on Saturday and said that although he wasn't sure whether clay was his best surface, he was certain that it was a test of 'real tennis'.
Rublev woke up and chose facts
