PARIS: Portugal have yet to win at Euro 2016 and face a testing last-16 clash against Croatia but Cristiano Ronaldo's first two goals at the tournament have filled the team with confidence.

Ronaldo scored twice and Portugal came from behind three times to earn a 3-3 draw against Hungary on Wednesday, a result that allowed Fernando Santos's side to progress from Group F as one of the four best third-placed sides.

Ronaldo was under scrutiny after a poor start to the tournament as Portugal drew their opening games against Iceland and Austria.

Portugal, who reached the semi-finals of the competition four years ago before losing to Spain on penalties, take on Croatia on Saturday in Lens.

Croatia beat Spain 2-1 on Tuesday to progress as top of their group.

"Against Croatia, it's going to be 50-50," said Ronaldo, who scored 51 goals in 48 games in all competitions for Real Madrid this season.

"Whoever plays better will go through. Few sides beat Spain and we know that we are going to face a good side and we have to win.

"We have our weapons and our courage and we will play them eye to eye."
