Portugal winger Nani is confident of his side's chances of going far at Euro 2016 despite failing to pick up a single win inside 90 minutes en route to the last eight.

Portugal winger Nani has talked up his side's chances of going far at Euro 2016.

Fernando Santos's side failed to win a single one of their group games, but still qualified for the knockout rounds and squeezed past Croatia courtesy of a 117th-minute winner from Ricardo Quaresma.

Portugal will now face Poland in the quarter-finals on Thursday, and Nani is expecting another difficult test.

"The group is excellent, young, all demonstrating team spirit, all pulling in the same direction and this has been one of the factors that shows we are stronger. We have all the conditions to go as far as possible. I think we have played good games, putting on a spectacle and against Hungary we scored a lot of goals - but, of course, it will not be possible to do this in all matches," he told reporters.

"We know that Poland is a very strong team, with experienced players, like [Robert] Lewandowski, but we have to focus on the team, not [just think] about one player because any player in this game can make a difference.

"If we can control all of the pieces on the pitch, I think we will have more chance than if we control just one player. We have to be at our best, to go in with the confidence to try and win the game."

Nani has scored two goals in four games for Portugal at this summer's tournament.
