Based on my research, here is my analysis of the claim:

Reasoning:

• Kylian Mbappé is indeed French and represents France internationally¹
• Multiple sources confirm that Kylian Mbappé leads the 2025-26 Champions League goalscoring charts with exactly 13 goals for Real Madrid as of April 2026²¹³⁴
• He is ahead of the next closest competitors Anthony Gordon (Newcastle United) and Harry Kane (Bayern Munich), who both have 10 goals¹³
• UEFA's official statistics page shows Mbappé ranked first with 13 goals in 9 matches played²
• ESPN confirms he "tops the Champions League goalscoring charts this season after the round of 16" with 13 goals¹

Overall validity: 100%
