Real Madrid will probably lose, because while they are having trouble at their league, Bayern is here hving fun and knowing that they already got the title. Bayern Munich should look a lot more rested and a lot more relaxed as well, less stress, les anxiety, and less to prove.
Real Madrid will of course play with all they have, but wanting to win is different from fearing of loss and what Real Madrid has right now is fear of loss, whereas Bayern Munich has wanting to win instead.
You have the same view as I. Bayern Munich are in better physical and mental form to win the game. I said physically because the players like Aurelien Tchouameni, Thibaut Courtois, and Rodrygo would be absent. Mentally, because Real have not had good times in the La Liga.
But we shouldn't forget that games like this are unpredictable because a single player in Real can change the course of the game. I remembered what Ademola Lookman did to Bayern Leverkusen in the Europa League Finals, which made Atalanta champions.
