However, I'm actually surprised that the Black Panther is (as of May 18th) the bottom answer... After all, before Figo and Cristiano Ronaldo came, he was Portugal's historic top-player.
Eusebio played for Benfica in the 1968 European Cup Final versus Manchester United. He was a great player and a great sportsman. In the 89th minute of normal time, with the score standing at 1-1, Eusebio was through on goal with a great chance to score, but the keeper made an excellent save. He could have won the match with that shot. He waited for the keeper to distribute the ball, and stayed to give him a personal applause. The keeper was called Alex Stepney. United went on to win in extra time, scoring three more goals, making them the first English team to win the European Cup. See here.
