Portugal coach Carlos Queiroz has told his team not to get carried away by their unbeaten run as they enter the last 16 of the World Cup.

The Portuguese take on European champions Spain on Tuesday in Cape Town after finishing second in their group behind Brazil and Friday's goalless draw against the South Americans marked the 19th consecutive game Portugal have gone undefeated under Queiroz.

But Queiroz said: "Statistics don't mean very much. They might build up our confidence, but we cannot go to the round of 16 just with reputation and statistics. Our players have to prove their worth on the pitch."
