Thank you, Alrel for the info!
That pollen allergy is very unpleasant but hopefully it only lasts during May and June.
It is even worse cause most of the medicaments for threathening it are considered dopping and he cant't do really much about that. We also didn't know that until he withdrew from his last match and his father explained it in an interview. His family here and Grigor rarely gave any interviews and are avoiding the press as match as possible. And the fans are very unhappy of this fact.
For the movement - it is a fact that Grigor has grown on high within last couple of years and is probably still growing. I got the feeling he hadn't adjusted his game stile to his new body yet and sometimes get off balance. He used to be not that high and moved better and smoother. This transitional period is really awkward and we don't know what will show at the end. Maybe if he focus on and practice movement with appropriate training as well as returns on serve he would do much better - these look like his biggest weaknesses so far. (I would recommend some yoga practices for getting more flexibility, balance and concentration
: as well as quick step dances
for the movement
with those big feet he has it would be fun to watch
The the more powerfull groundstrokes will come with the better fitness. I don't worry much about that!
Tell him if you can, that we really support him in good and bad times!
Good luck, Grisho
