Chelsea defender Toni Rudiger says Germany may need to go ugly to beat Euro opponents France.
Germany face a tough group with Portugal and Hungary their other two opponents alongside the World Cup winners, who are considered by many to be the favourites.
"Of course, they have good forwards, we have to be ready to win the one-on-one challenges," Rudiger said ahead of the game.
"We have to be a little dirty, not always be nice or try to play nice football.
"Against players like them, you have to throw down a marker."
Mbappe was asked about Rudiger's comments in his following press conference and insisted his team will focus on playing their own style of football
"Each man fights with the weapons at their disposal.
"Our weapons are to play together, to play our game. If those are their weapons, then they will play with theirs, we will play with ours.
"And we remain focused on our preparation, analysing well what their strengths and weaknesses are, and to try to begin this tournament well."
