That's true. I have heard some stuff about him, and people were also calling him Haaland in the making. He's 1.85m and super fast, and also, he's very versatile in the offense. 30 million looks so bargain if we compare him to the other striker. I still consider 30 million quite cheap to get a potential talent like him.
Borussia Dortmund is very smart to trade the 31-year-old Füllkrug for the 21-year-old Beier. It's incredible to see the way Dortmund is regenerating its players. Beier could potentially be the next Haaland, and they can sell him for 90m at least
Dortmund will make him hone his skills so that he can be like the strikers who have been honed by the club before Erling Haaland and Robert Lewandowski, after that Dortmund can sell him to a top club.
Dortmund has always been an intermediary for players who have potential so that they can become star players. Dortmund is also very good at negotiating to get quality players at low prices, especially since he is still very young, so the player can be used as a long-term investment. He signed a 5-year contract and has enough time to show his talent more.
