I think most people also guessed he will move to Bayern Munich or Real Madrid. However, Florian Wirtz may consider another aspect, he wants to play in a more competitive league and joins a team that is suitable with his play style. Liverpool may be a perfect team that meets his dream for the future career as a footballer. I think it is no problem as long as he joins one of the top teams in the world.
Yes, his age is still relatively young, where Florian Wirtz is still 22 years old, so his future is still quite long, he can still try out the leagues in Europe as long as he is able to maintain his health and posture well, like CR7 who is still active as a professional footballer at the age of 41 years.
And what is surprising is the transfer value of Florian Wirtz to Liverpool, breaking the player transfer record in the English league, making him the most expensive young player in the English league.
