João Lucas

Born in Caldas da Rainha, Leiria District, Lucas began his career at Académica de Coimbra, making his professional debut during the 1999–2000 season (two matches in the Segunda Liga) and also being loaned twice to amateur clubs, after which he returned to become an important first-team member. In 2004–05, Lucas signed with Boavista FC, where he consistently performed during three Primeira Liga seasons. On 3 February 2006, he scored his only official goal for the northerners, in a 3–0 league home win against Associação Naval 1º de Maio. In the 2007 summer transfer window, Lucas joined Serbian giants Red Star Belgrade. However, on 17 March 2008, he announced his decision to stop playing football, as the 28-year-old had heart problems and the doctors told him he would risk his life if he continued playing. "This is the most difficult moment of my life but I have to thank everyone at Red Star who stood by me in the past two months", he told in a news conference.
