The serving and serve receiving preparation that Nadal employs is really baffling. Why on earth would somebody be so superstitious that they feel they have to tug at their underwear and then wipe the same fingers on their nose and then tuck some hair from the outside of their ears to the inside or having short hair feel the need to touch their ears?
Strange
This is common thing among famous athletes, most of them have weird superstitions. Observe tennis players and you will see that they often have some weird ceremony before serve. Very common is also that they dont step on any lines. Serena Willaism doesnt change socks between matched, she always uses same ones, Federer always have 8 racquets and uses 8 bottles of water, Jordan wore same shorts under his main one from 1982 up until end of his career.
