Rafael Nadal’s hopes of a 15th grand slam title were crushed by an inspired Roger Federer in the Australian Open final on Sunday but the rejuvenated Spaniard was already rubbing his hands together with the prospect of a “special” season on clay. Nadal battled back twice from a set down and held a 3-1 lead in the deciding fifth but was powerless to stop Federer’s victory charge and bowed out 6-4, 3-6, 6-1, 3-6, 6-3 at Rod Laver Arena.
