Wimbledon 2015: Rafael Nadalâs coach says itâs good to talk during play. Toni Nadal feels that coaches are getting a rough deal. Toni Nadal, the coach and uncle of Rafael Nadal, believes it is impossible for a coach not to encourage and communicate generally with a player during a match.
After this win, his uncle intensified Nadal's training and encouraged him to play left-handed to give him an advantage on the court. When Nadal was 12 years he won the Spanish and European tennis titles in his age group before turning professional at the age of 15 in 2002. He participated in two events on the ITF junior circuit and reached the semi-finals of the Boy's Singles tournament at Wimbledon in the first of these at the age of 16.
