"I feel extremely excited, I don't know how I will wait until Sunday," said Grabar-Kitarovic, who is going to attend the game.
"Regardless of Sunday's result, which I believe will be a victory, we are winners." She said the current set of players had surpassed the achievements of the team that finished third at the 1998 World Cup in France.
Police in Zagreb said they would be working extra hours to process passports from fans wanting to attend the match.
Grabar-Kitarovic said she would probably give a Croatia jersey to her French counterpart Emmanuel Macron after sending one to Russian President Vladimir Putin and giving one to British Prime Minister Theresa May earlier in the tournament.
"I hope for fair play and a good atmosphere," she added, but did not want to predict the result.
"I'm not good at that. The result is not important, only that it is a victory."
Regardless of the outcome, the team will be welcomed on Monday at 2:30 pm (1230 GMT) in Zagreb's main Jelacic Square.
Tens of thousands of people are expected to greet the team on their way from the airport to the city centre.
