France won their second title, following 1998 - when they had beaten Croatia 2-1 in the semi-finals - and made up for the disappointment of losing the 2006 final to Italy on penalties, and the Euro 2016 decider at home to Portugal.
Early in the second half, Rebic forced goalkeeper Hugo Lloris into his first real save of the game as he hammered a shot from a tight angle that was tipped over.

"It serves a lesson to us, and it means we know what it is to play in a final", added Matuidi.

After all, she won two of them, helping the US win its first in 1991 and its second in 1999, scoring two goals in the latter tournament.
Against England in the Semi-Final, Croatia fell behind 2-1 only to score late to tie the game and then again with 5 minutes left in overtime to clinch the win.
With the Jules Rimet trophy on the line, this thrilling winner-take-all contest between France and Croatia is one that fans are super thrilled about.
