Career
He had no football experience when he was announced as the choice of then President of the Portuguese Football Federation, Silva Resende, for manager of the Portuguese national football team, after the disappointing presence at the 1986 World Cup finals, mostly due to the Saltillo Affair. Seabra was officially the team selector, while Juca would be the coach for the Union of European Football Associations Euro 1988 qualifying. After the 2–2 draw with Malta, Seabra resigned and Juca assumed full functions for the rest of the qualifyings.
