Portugal came close to scoring in the seventh minute, when Cristiano Ronaldo latched onto a through ball down the left, before moving past one defender, but his right-foot effort went slightly over the bar.
Four minutes later, Portugal produced more danger through a fast counter-attack that found Ronaldo without marking, but the Real Madrid ace’s shot went straight at the keeper.
Denmark responded in the 16th minute as the ball luckily found the path of Jacobsen but the midfielder, with only the keeper to beat, could not direct it goalwards from close range.
In the 21st minute, the visitors wasted another chance. A low cross from Duda down the left found Simao, who did well to control the ball but his shot was weak and went straight into the hands of the keeper.
