Ex-Miss Croatia made a huge promise to fans if they went on to win the World Cup

The former winner of Miss Croatia made a huge promise to the country prior to their semi-final exit after a defeat by Argentina.

They have also become masters of extra time and penalties, having required more than 90 minutes in every game leading up to the final four years ago, and again in the current tournament.

Former Miss Croatia, Ivana Knoll, has been the centre of several headlines, due in part to her quite incredible clothes in the colours of the national flag.

Prior to their clash against Argentina, Knoll offered an extra incentive for Zlatko Dalic's men to go all the way.

Asked by German press what she'd do if Croatia become world champions, Knoll, who was wearing a Croatian flag at the time, said, "If that happens, the flag falls…" promising to go naked as a reward.

The 30-year-old's style has gone against many of the rules in the Arab country, in which both men and women are meant to cover up.

She has previously claimed that she wasn't aware of the rules, saying, "First I was thinking if the World Cup is happening there, they for sure will allow everything to make it comfortable for all fans without any of their restrictions.

"Then I heard about the rules and I was shocked. In the dress code, you’re forbidden from showing your shoulders, knees, belly and neck.

"I was like, ‘OMG, I don’t even have clothes covering that all.'"

However, her promise will not be fulfilled as Lionel Messi inspired his country to a 3-0 victory over Croatia.

Argentina will now face either France or Morocco in Sunday’s final.
