Martinez's side still have the opportunity to turn the tides in the tie when the two sides meet in the second leg on Sunday, March 23. The Belgian coach claims to have understood the reason for the loss and aims to have a good game in the second leg. He added: "Was there a lack of intensity? Yes. We didn't win the duels we needed to win, we didn't anticipate the areas where Denmark likes to play inside, to create numerical superiority in the central zone. There was a lot of loss of the ball, there was a lack of quick passing lines and that happens at the club every day, every game, then you work and improve. There was a lack of synchronisation. The attitude was fantastic, but our performance was not at the level we expected and the players are very focused on using the support of Alvalade to show what we can do."
