Griezmann, who was named man of the match, scored the opening goal from the penalty spot in France’s 2-1 win against Australia in Russia's Kazan on Saturday.

"The first match is always hard. I'm glad that we won. Australia are a difficult and well-organised team. They can be serious rivals for Peru and Denmark as well," Griezmann told journalists.

France will next face Peru in Yekaterinburg on June 21 and Denmark in Moscow on June 26 in Group C.
