At the 2018 finals in Russia, Zlatko Dalic led a nation with a smaller population than that of Scotland to the zenith of international football when they contested the World Cup final. They would come up short against France on the day.
Croatia reaching that showpiece was a surprise, but Modric is the very embodiment of upsetting the odds.
He and his family had to flee their home near the Dalmatian city of Zadar due to the Croatian War of Independence that provided the backdrop to his childhood.
As a Dinamo Zagreb graduate, 20 years ago, he was sent on loan to Bosnian club Zrinjski Mostar. For a young Croatian, that will have been an eye-opener.
In the ensuing two decades, Modric has won six Champions League titles, five Super Cups, four Spanish titles and five Club World Cups alongside the 180 caps he has proudly amassed in Croatia’s red and white checks.
Yet, when he made big-money moves to Tottenham Hotspur and Real Madrid, where he has won anything and everything, he was written off by many. He is currently enjoying his 13th season at the Santiago Bernabeu.
“I’m still here, motivated as before,” Modric said last month. “I am most proud to play for Croatia. I think I can still help.”
He was right as he followed up that statement with a complete masterclass against Poland on matchday two in Osijek in which he scored the only goal of the game with a superbly executed free-kick.
Scotland actually have a winning record against the Croats and are unbeaten on their two previous visits to Zagreb.
However, their two victories during the 2014 World Cup qualifying campaign, including an unexpected triumph in the Croatian capital, came after the qualification horse had long since bolted.
More recently, the Scots were on the receiving end of Modric wizardry in what was their must-win final group match of Euro 2020. Croatia eased to a 3-1 victory at Hampden Park, with the veteran scoring the second, and the game exposed a big gap between the teams.
To remain in contention in the current Nations League section and maintain hopes of a place in pot one or two for next year’s World Cup qualifiers, this is a game Scotland will probably have to win.
The trouble is that Croatia do not lose at home very often. That Scotland victory 11 years ago is one of only seven competitive defeats suffered on their own soil since Croatia entered the Fifa rankings in 1994.
Like Scotland, they had a disappointing European Championship in Germany, exiting at the group stage after conceding late goals against Albania and Italy in a tough group. Eventual winners Spain topped the section.
However, that anti-climax does not detract from the fact this will be a very tough assignment.
