Why would he regret this move?
He will now be seen around the world more often because Real Madrid is a bigger team than PSG and his goals and contributions will now make him more relevant in football than he has been. He will surely perform well for Real Madrid and will win a lot of trophies is the team is back on their feet.
Being one of the best players in the world, and being in the best club in the world, yes I agree that there is nothing to regret for K. Mbappe. And even though this season Real Madrid has not lifted a single trophy, but by being in Real Madrid, K. Mbappe gets more stage in world football.
They just need to stabilize their defense. Xabi Alonso has time to set up a winning squad. With Mbappe up front, they have a great chance of winning all three trophies. So all in all, Real can get back to their old winning ways.
"La Barba Roja" or the red beard is the nickname given to him by the Spanish media. After starting his coaching career by handling Real Sociedad B in 2019, and going to the Bundesliga to handle Bayer Leverkusen for three seasons and making a surprise there, now he will return to Spain. Not returning to coach Real Sociedad B, but he came to coach one of the best clubs not only in Spain but also in the world.
When he was still coaching Bayer Leverkusen, with the existing player material, he managed to bring Leverkusen to win the championship trophy for the first time in history. So of course there is great hope, with the presence of Alonso at the Santiago Bernabeu, this will rekindle the enthusiasm of the players to be able to win more trophies.
