Kylian Mbappe has revealed he played with a back injury in both the semi-finals and final as France won the 2018 FIFA World Cup in Russia earlier this month.
The 19-year-old scored as Les Bleus beat Croatia 4-2 in the final, and he said the team and coaching staff kept his injury a secret on purpose, per France Football (h/t The Independent): "It was essential not to alert our opponents, otherwise they could have taken advantage of that and targeted this sensitive area. That's the reason why with the staff and the players we kept it hidden, even for the final.
