He got a standing ovation and hero’s welcome last time he was there with Madrid and it affected his game (ofcourse he still bagged the winner on the day, which is standard really, but he didn’t perform close to his usual level).
Don’t think he’s used to playing in front of a crowd where he almost literally has 0 haters.
Ronaldo performs at his best when he’s a little on edge or has a little chip on his shoulder.
I think I remember watching highlights of that game and he was even saying as much in his post match that the welcome and applaud made him feel “a little bit shy.”
Hopefully it doesn’t do the same today.
