Illness: Severe Gastroenteritis

According to AS, Mbappé suffered an acute case of gastroenteritis upon arrival in the U.S., which led to significant weakness, weight loss of over 1 kg (~2.2 lbs), and even hospitalization in Florida for two days  .

The extreme heat (feels like 37–38 °C in Palm Beach) has slowed his recovery process  .


Recovery Progress

He has been performing individual, indoor training; he did not take part in full-field team sessions and instead focused on gym work and conditioning  .

Real Madrid’s medical staff have emphasized that they will only field him based on his physical condition—not schedule pressures  .


Matchday Status: Unlikely to Play

Marca officially reports he is not expected to play against Salzburg, with his inclusion hinging on substantial improvement within the next 24 hours  .

Spanish journalist Edu Aguirre noted that while there’s medical consideration for calling him up as a substitute, starting seems off the table—“he’s very weak”  .

📌 What This Means for the Team

If Mbappé fails to show marked improvement in the final training session before the match, he will be left out of the squad or at best used off the bench  .

Real Madrid coach Xabi Alonso and the medical staff will make a final decision after tomorrow’s (Wednesday) session  .

⚔️ Strategic Implications

Mbappé has missed the first two Club World Cup matches due to fever and this illness  , during which academy forward Gonzalo García stepped up  .

Real only needs a draw to secure progression from Group H, so they might opt for caution and prioritize ensuring Mbappé is fully fit—both physically and tactically—for future knockout rounds  .
