Arsenal remain without key names: Gabriel Jesus, Kai Havertz, Takehiro Tomiyasu, and Gabriel Magalhaes are sidelined, while Riccardo Calafiori is injured and Raheem Sterling suspended. However, there’s a boost with Bukayo Saka expected to start after recovering from injury, joining Merino and Martinelli in attack. Mikel Merino, who suffered a head injury at the weekend, should be fit to feature.

Real Madrid are also contending with absences. Aurelien Tchouameni is suspended, while Carvajal and Militao are long-term casualties. Goalkeeper Thibaut Courtois faces a late fitness test, with Andriy Lunin on standby. Fortunately for Ancelotti, Mbappe, Vinicius Jr., and Rudiger are all available despite recent disciplinary concerns, and Ferland Mendy is likely to return.

Real Madrid’s European pedigree cannot be overstated, but Arsenal's home form in the Champions League has been rock-solid. Missing Gabriel may limit Arsenal’s aerial threat, especially against a vulnerable Real defence, but their midfield steel and attacking flair should keep them in the fight. Expect a tightly contested game where both sides cancel each other out.
