Okay fine, maybe when he plays matches too. I am not a Dolgopolov expert, Sanya.
I just read a couple of interviews when he said that that after travelling he feels ill and cannot play matches, and never read when he actually plays matches he feels it.
Thank you, Helvorn for correcting me.
The thing is, if he feels it only sometimes, as a viewer you can never know when it is affecting him and when it is not.
Well he doesn't really pull out anywhere, so he obviously can play matches, the only thing he doesn't play because it's too much of a strain is Davis Cup.
