Three years ago, Novotný said that he was giving Nadal three years due to chronic knee problems. Nadal's current situation confirms that the Czech doctor was not that far from truth.
Petra knows enough English now, where she shouldn't have to keep her team exclusive to Czech's.
I think that's been part of the problem of her maturation in the first place. It just keeps Petra in her little sequestered comfort zone.
Djokovic, may be surrounded by a lot of Serbs (and could even be wary of the US/West Politically-cause of what happen in his country-though I don't know). However, he's a very out going guy with the English speaking media, his sponsors, and marketing responsibilities. He may even have consulted non-Serbian nutritionist, coaching/fitness and physicians for all I know.
Petra just needs to hire the best people. If other player relationships can take disparate individuals from around the world placing them together--create working relationships on the regular, Petra can to. They need to stop babying her.
Yes, Katie's a good start. However, I'm sure it wasn't Petra's (or her camps) idea in the first place. But I could be wrong. Nonetheless, kudos for the decision, cause the exposure appears good for her.
Petra's just too much sometimes.
