Shamil T said in "Game.Set.Match" the other day that Korolev had wrist problems like Dima.
I doubt Zhenya was in a position to say no to Shamil.
Plus he likes to play on clay.
Umm, I don't see anything wrong if Marat plays some clay matches before the US spring season instead of indoors in Europe. Serves him right!
Then he might not be as pathetic on clay coming back to Europe for the clay tourneys.
