Trent Alexander-Arnold misses out for Real Madrid today through injury, while fellow defender Dean Huijsen is suspended.
Kylian Mbappe starts for the first time in this tournament, against his former club, with Raul Asencio also coming in. Federico Valverde moves to right-back in a tactical shuffle.
Real Madrid XI: Courtois, Valverde, Asencio, Rudiger, F García, Guler, Tchouameni, Bellingham, G Garcia, Mbappe, Vinicius.
Kylian Mbappe and Ousmane Dembele were team-mates not long ago. Real's Mbappe and PSG's Dembele haven't started a game at this tournament for one reason or another. Are they both starting this?

PSG v Real Madrid (20:00 BST)
Remember the very start of the Club World Cup all the way back in mid-June?
Well, the tournament is drawing to a close, with the winner of this European super-heavyweight showdown joining Chelsea in Sunday's final.
PSG and Real Madrid both have line-ups coated in star dust.
But one of these two teams, who have each battled through five matches in the United States to reach this point, are heading home empty handed after this game.

Paris St-Germain demolished Real Madrid to set up a Fifa Club World Cup final against Chelsea on Sunday.
This semi-final tie at the MetLife Stadium was over as a contest within 24 minutes as the Champions League winners tore the Spanish side apart.
Fabian Ruiz tapped in the sixth-minute opener following a big mistake from Real defender Raul Asencio - after the referee let play continue following Thibaut Courtois' foul on Ousmane Dembele.
French winger Dembele raced away three minutes later to finish calmly after a mis-kick from Antonio Rudiger.
Ruiz then slotted home the third after a fantastic give-and-go between Achraf Hakimi and Dembele.
Real, who were missing the injured Trent Alexander-Arnold, offered little in response and Goncalo Ramos added a late fourth for PSG to cap a dominant display.
What was the main talking point?
PSG's all-time top scorer Kylian Mbappe was on the pitch to witness another masterclass… by his former side.
Since the France striker left for Madrid a year ago on a free transfer, PSG have become an infinitely better team and are looking to make the Club World Cup their fourth trophy of 2025 (five if you count France's version of the Community Shield).
And despite a combined 48 goals and assists from Mbappe in 2024-25 for Real, they have ended the campaign without a trophy.
No team can handle the pace, passing and pressing of Luis Enrique's PSG side, who thrashed Inter Milan 5-0 to win the Champions League and have beaten Atletico Madrid 4-0, Bayern Munich 2-0 (with nine men) and now Real Madrid 4-0 in the United States.
Ruiz scored twice but his midfield partners were fantastic too. Real could not handle PSG's front three, nor Hakimi at right-back.
There was an emotional goodbye for 39-year-old Croat Luka Modric, who made his 597th and final appearance for Real and will join AC Milan now.
The standout stats
Dating back to the Coupe de France final, PSG have won their last five knockout round matches in all competitions by a combined score of 18-0.
Real Madrid, who had never lost a Club World Cup match before, conceded three goals in the opening 25 minutes of a match for the first time since 9 November 2003 against Sevilla in La Liga.
What is next for these teams?
PSG play Chelsea in Sunday's final, which will also take place in New Jersey. They have back-to-back games against London sides, starting 2025-26 off with the Uefa Super Cup against Tottenham on 13 August.
Real Madrid will not be action again until their opening La Liga game. At the moment that is due to be at home to Osasuna on 19 August, although Real are trying to get that game postponed to give them a longer break.
