Despite being Real Madrid's top scorer with 38 goals this season, Mbappé has been struggling with a knee injury in recent months. The 24-year-old's condition has deteriorated to the point where he will be unavailable for the crucial tie against Benfica.
Madrid's medical staff have been monitoring the situation closely, but the persistent nature of the injury has forced the decision to rest their star attacker. The club will hope the extended rest period allows Mbappé to return to full fitness for the latter stages of the season.
