Casillas, who is brand ambassador for Hisense's UEFA Euro 2024 campaign BEYOND GLORY, told the Daily Mail: "He's made it at the most important club in the world and has shown that he's a great player and that he can be there. Now, and next year, more may be asked of him, but that's what will make him a star. He could surely be the captain of Real Madrid, of course. He has everything to form the part.
"There are more experienced people at the top, but I would advise him to continue learning from the other veterans there, to continue soaking up the history of the club, and to do everything to be a great player and captain."
