Rafael Nadal was asked if he believes that more Masters 1000s should introduce a roof on the Central Court.
The Spanish player said: "Honestly with the Grand Slams are great that they are doing this stuff because is better for the fans, is better for the tournament by itself. Honestly, here in the Masters 1000s, okay, if you have it, better.
I don't think is something totally necessary. If you have it, better. If not, I think the tournament is good like this."
