Ronaldinho is fighting to save his Brazil career and head to the World Cup this summer, says his brother and agent Roberto De Assis.His resurgence at Milan has been overlooked by Selecao coach Carlos Dunga, having been snubbed for the friendly against Ireland last week. Dunga has made it clear that 'Dinho's place is less than guaranteed.But that has not discouraged the ace, who has made it his personal objective to prove the coach wrong."I am supporting Ronaldinho and I hope he takes part in another World Cup," De Assis told SporTV."He is working hard as he waits for a call. Every athlete at this level always thinks about this possibility. His dream all his life has been to wear the Brazil shirt."Brazil kick off their World Cup adventure on June 15 against North Korea. They then meet the Ivory Coast five days later, and finally Portugal on June 25.Source: Kickoff.com
