Denmark are confident they can continue a good run of results against Portugal and shut down dangerman Cristiano Ronaldo when the sides meet on Wednesday in their second Euro 2012 game. 
Denmark, surprise joint leaders of Group B, won their qualifying section ahead of Portugal, largely due to a 2-1 home victory over them.
"We have closed down Cristiano Ronaldo before and we firmly believe we can do it again," said defender Simon Kjaer, one of the Danes' best performers in a surprise 1-0 win over Netherlands in their opening game at the finals.
"He has got unique individual skills but we have shown before that we can cope with him as a team and we believe that we can defeat Portugal again," Kjaer told reporters.
Midfielder Michael Silberbauer man-marked Ronaldo in Copenhagen and is set to start in place of Simon Poulsen.
Denmark had lost the Euro qualifying away game 3-1 in Lisbon. They were also in the same qualifying group as Portugal for the 2010 World Cup, winning one game and drawing the other.
The Danes, the ninth-ranked team in the world, were initially tipped to go out in the first round of Euro 2012 but 10th-ranked Portugal have lost their way recently and now look vulnerable.
Although coach Paolo Bento insisted he was happy with the performance against Germany, he will be under pressure to rework his misfiring forward line.
