he's good, but not int he league of the players mentioned. long way to go. the higher up you are the tougher it is to move up in rankings.
the good thing about yesterday's match is that he managed to get back on track after his meltdown. that's a good factor.
let's see what he looks like against Almagro, a player far ahead of him in the rankings.
