Argentina as defending champions opened the 1990 tournament in Italy against a Cameroon side that had few recognised stars. However, Francois Omam-Biyik's headed goal, helped by an awful goalkeeping error by Nery Pumpido, gave them an astonishing 1-0 win in a game that their raw tackling saw them reduced to nine men. "We hate it when European reporters ask us if we eat monkeys and have a witch doctor. We are real football players and we proved this tonight," said Biyik.
