Mentally, I wouldn't say he is week. He is very young and he is improving rather rapidly. In the review of yesterday's match on http://www.wimbledon.org/en_GB/news/...928489781.html
they said that he is the rising star. And he is!
Physically, he needs to gain a few pounds and to pump up his muscle mass, to work on his endurance and strenght, although he is alredy pretty strong.
Coming back to the "mental point"
, I saw the match yesterday and I knew that he had a shot! It was that one moment in the 4th set when he could have broken Mario but he didn't...
He already has a huge experience considering that he has just recently turned 19, and when he takes a break, and realizes what he has accomplished in the last year, I believe he will start looking at himself and his game in a different way...building up his self-confidence and than he will be unstoppable
Because he has the game to beat any player!
And watching him take a shot at Rogerer would have been spectacular!!!
But, we'll have to wait for the next year's Wimbledon!
