Croatia scored twice in extra time to beat the Netherlands 4-2 in their Nations League semi-final in Rotterdam on Wednesday and advance to Sunday's decider.
Croatia will play either Italy or Spain, who face off in the second semi-final in Enschede on Thursday, for a first major title as they continued their form from last year's World Cup in Qatar, where they finished third.
Substitute Bruno Petkovic curled home a stunning shot from the edge of the penalty area eight minutes into extra time to put them on their way.
And Luka Modric made sure of Croatia's triumph with a late penalty, their second of the game.
The Dutch, hosting the four-nation tournament, had forced extra time with a last-gasp equaliser to ensure it finished 2-2 after 90 minutes despite being largely outplayed in front of their home fans at the Feyenoord Stadium.
Donyell Malen handed the hosts a 34th-minute lead before Andrej Kramaric equalised from the penalty spot 10 minutes into the second half.
Croatia then went ahead through Mario Pasalic in the 73rd minute before Noa Lang side-footed the ball into the roof of the net to equalise six minutes into stoppage time.
