“We are going to play a cautious game because we respect Sporting,” he told Uefa.com. “However, we will play with ambition because we want to collect the three points at the Alvalade.
“This is not the best time to face Sporting. This is not our best moment and this is also the first group stage match. But hopefully we can get the result we want.”
Queiroz, Cristiano Ronaldo and Nani will all be returning to face their former team on Wednesday.
“Of course it will be a special feeling playing against Sporting, as it will be for Nani and Cristiano Ronaldo,” he said.
“But we are all professionals and I am sure we will do our best. I hope we can play a tremendous game and I’m sure the Sporting fans are expecting this.”
