I think Bayer Leverkusen wants to send Wirtz to another team. Because they will be in the Champions League next year and they also want to be champions in the Bundesliga. Their biggest rival in the Bundesliga is of course Bayern Munich. They don't want Bayern Munich to get stronger, so they offer them a different price. In my opinion, this is a situation that arises from the competition between the clubs. It is normal for such things to happen in football because you don't want your strongest rival to get stronger and you don't want them to get stronger by taking your best player.
That's why Leverkusen gave a fantastic price for Wirtz if Bayern Munich wants to recruit him. But I don't know if the rumor is true that Leverkusen gave a price of 150 million euros if Munich wants to recruit him and 100 million euros if it's another team. But I think for now Wirtz's market value is still very high. Yes, he is one of the best talents in the world today. He is still 22 years old and that's why many top clubs in Europe want to get him. So far I heard rumors that City, Liverpool and Munich are negotiating to get Wirtz. But City seems to have canceled their intention because the estimated deal value reaches 250 or 300 million euros and I think that really doesn't make sense.
