Only Reinier Jesus has been absent from training this week, as the 20-year-old seeks to continue his development on loan elsewhere in the 2022-23 season, but Rodrygo has since picked up a small muscular problem.
A full-strength XI took to the field on Wednesday in the UEFA Super Cup success over Eintracht Frankfurt, so Ancelotti may ponder a change or two here.
UEFA Men's Player of the Year nominee Thibaut Courtois will start in goal as ever, while Antonio Rudiger is pushing to be involved in the heart of defence but could lose out to David Alaba and Eder Militao again.
Ancelotti must take care over Ferland Mendy and Dani Carvajal following their injury woes last term, but the duo should be fine to feature from the off here, as Rudiger waits patiently for his opportunity.
Casemiro, Toni Kroos and Luka Modric should form the timeless midfield trio, as Aurelien Tchouameni and Eduardo Camavinga also wait to provide fresh legs from the bench.
Karim Benzema - another UEFA Men's Player of the Year nominee - should be supported by Vinicius Junior as ever, and Federico Valverde should hold his place on the right in the absence of Rodrygo.
Real Madrid possible starting lineup: Courtois; Carvajal, Militao, Alaba, Mendy; Kroos, Casemiro, Modric; Valverde, Benzema, Vinicius Jr
