As much as I love tennis and as much as I admire Rafa's play, I had to stop watching him about two or three years ago. Apart from his scratching, ball bouncing, clothing adjustments, hair grooming, have you noticed that his water bottles have to be equidistant apart beneath his chair with all the labels centred to the front? And nobody, but NOBODY, must touch them.
I caught a glimpse of him recently and he really has got far worse. He really has some serious psychological problems and he should seek immediate help for them asap. Once he stops playing tennis he will have no outlet for these ridiculous foibles and they will manifest themselves somehow else in "ordinary" life with possibly life-ruining consequences.
