Addressing the press on Tuesday, Tchouameni publicly backed his French national team-mate to produce the goods for Real Madrid.
"It's incredible talking about 'difficult days' for [Mbappe]," Tchouameni said (h/t ESPN). "Because he didn't score in two games? We know that if he scores a goal or two tomorrow, everyone will be saying 'he's an incredible player.' For us professionals, the most important thing is the next game. Kylian doesn't need advice, he's scored a lot of goals and he will score a lot of goals.
"Honestly Kylian wants to win and score goals every game, so there's no extra motivation. He wants to be at his best level all the time, there's no difference."
