Even when Mbappe missed UCL trophy on his first season at Madrid. It won't change he has greater chance to win UCL trophy in the next season. He loves UCL trophy as he has not yet won it, but he's in a club which often dominated UCL. Why should he regret it when he failed to get UCL on his first season at Madrid?
His bad season with Madrid can't deliberate the fact he and his team will always be the favorite to win UCL in another season. He's not playing at netflix FC who never won trophy, and there's nothing to feel worry about.
Best of luck him next season by performing better under a new coach.
Real Madrid is one of the best teams in the world, they did not win any titles this season but what must be believed is that Real Madrid management will not remain silent, they will make many changes for next season which is already visible is the arrival of a new coach so I also think that no player regrets when they are already at Real Madrid to be able to win the title unless the player does not get playing time.
This is different from Mbappe, in his first season Mbappe has scored many goals and now he will be the hope for next season.
