Mbappe Vows to Improve Defensive Efforts Ahead of World Cup Opener

France captain Kylian Mbappe has vowed to increase his defensive efforts as the two-time world champions prepare to get their World Cup campaign under way against Senegal on Tuesday.

The 27-year-old Real Madrid striker has faced scrutiny over both his performances and leadership for club and country, with international team-mate Ousmane Dembele publicly backing him, saying that the criticism had gone "too far".

Speaking to French newspaper La Parisien, Mbappe faced questions from team-mates and friends, and when teased about his defensive ability by younger brother Ethan, who plays for Ligue One side Lille, he acknowledged that he has work to do.

"I need to take the extra step [with my defensive work] because it's something important for the team and I have to do it," he said.

"It will start this time because we want to win, and to win, I'm ready to do whatever because I want to win at all costs."
