France captain Hugo Lloris rejected the notion that transfer speculation surrounding international teammate Kylian Mbappe might affect his focus.
Didier Deschamps' team fell behind in Bucharest on Monday but Karim Benzema scored twice before Paul Pogba added a third to leave France seemingly on course for the quarter-finals.
Tottenham goalkeeper Lloris says Les Bleus need to prepare themselves for a different challenge on Saturday in front of a big crowd at the Puskas Arena in Budapest.
Didier Deschamps' France dominated possession but struggled to create any clear-cut chances against a determined Denmark.
Like the rest of his team-mates, Mbappe failed to impress on Saturday in France's crucial 1-0 win in Bulgaria.
