You can argue in many ways this move, but one thing is for sure: there are not many high quality coaches out there right now that can bring what Federer needs at this moment. Federer has been dealing with many issues like his health, and confidence is not as high as the past four years, plus entering the clay season makes it even tougher. That's why I think Higueras will bring Federer back to a high confidence level, and more importantly Higueras knows how to win on Clay!!
Federer wants that French Open real bad!!
Was it a good move? We'll have to wait a few weeks and see.
