Real Madrid playmaker Modric was influential as Croatia came from behind to beat Gareth Southgate's side 2-1 after extra-time in the semi-finals of the 2018 FIFA World Cup in Russia.
A generation of exciting young talent will try to help England right that wrong at an expectant Wembley, with Chelsea star Mount one of the leading lights.
No Englishman created more goalscoring opportunities than the 22-year-old's 87 in the Premier League in 2020-2021.
Mount ended the top-flight campaign with six goals and five assists before laying on Kai Havertz's winner in the UEFA Champions League final against Manchester City.
Chelsea secured its place in the continental showpiece with a 3-1 aggregate semi-final win over Madrid, and Mount enlisted the help of club team-mate and Modric's international colleague Mateo Kovacic to secure a prized possession – the Ballon d'Or winner's shirt.
"Ever since he was in the Premier League with Tottenham [Hotspur], I have watched him quite closely," Mount said of Modric.
"Playing against him, it was weird because I had watched him so much. I kind of knew his moves and what he was going to do."
Speaking at a pre-match news conference, Modric reprised the row over Croatia's impression of English arrogance at Russia 2018 in the form of the "It's Coming Home" slogan – the chorus line from the UEFA Euro 96 song Three Lions, despite it largely being used in self-deprecation by England fans.
"That arrogance is not so much related to the players but the people around them, some of the journalists and commentators," he said.
