Uncle Toni open to coaching change for Rafa

Rafael Nadal's coach and uncle, Toni Nadal, has not ruled out the possibility that the 14-time Grand Slam champion might seek a new or expanded coaching team in a bid to arrest his slide in form.

Nadal lost in the first round of a Grand Slam for just the second time in his career - to fellow Spaniard Fernando Verdasco - at the Australian Open on Tuesday.

"I understand that in sport results come first and if you have to make a change, you have to do it," Toni Nadal told Spanish radio station Cadena Cope on Wednesday.
