a winning formula of what ? what did he win actually in last 2 years?
it takes a while to remember and it's not impressive for his talent
he qualified for a grand slam at 17 and won it at 20 so by no means is he a weakling. He is just surrounded by losers and a bad advice. He looks lost for a couple of years now and is losing badly and hopelessly largely by himself.
a terrible coach who looks fat,clueless and unmotivated and is turning Nole into a hopeless case as well. Asthma can be cured of course as it's related to mineral deficiencies and nutritional imbalances. You can't excuse this guy because he is there at his every match and it doesn't matter. Nole was already a good player before he met with him but he is now worse than ever and looks hopeless as well.
So basically, you are blaming the coach for not giving Novak oncourt coaching, ie: cheating?
Get outta here.
