"Here they are in the quarter-finals, where nobody expected them to be. They deserved that if you ask me. We expect a difficult match against them. We'll have to be much better than we were against Denmark, which I'm confident we will be," the Croatian player stated.
Modric added that fans' support helped Russia get through to the quarter-final beating Spain, who were considered to be favorites to win the match.
"They are the host team, very strong, they work hard and fight as a team. They showed that against Spain, they were underdogs with very few chances. In the end, they survived the penalties, with the help of the home fans. They run and fight a lot, they were rewarded for that," the 32-year-old player said.
The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the final set to be held at Moscow's Luzhniki Stadium.
