Substiture Ricardo Quaresma scored a dying-minute goal to help the 2004 runners-up to trounce the Czech Republic 3-1 in Geneva on Wednesday.

The Porto forward scored the quick free-kick work to catch the Czechs out in the first minute of the stoppage time, as Deco put Cristiano Ronaldo clear but the latter unselfishly squared for Quaresma to wrap up the game.

An eight-minute goal by veteran Deco and a cracking strike from Ronaldo on the 63rd minutes, however, had earlier put Portugal in ahead, though Libor Sionko's header at 16 once denied the earlier lead of Luiz Felipe Scolari's side.
