Several European clubs, including AS Monaco, Chelsea, RB Salzburg, and VfB Stuttgart, are monitoring 17-year-old Malik Jakupovic of the Philadelphia Union. Borussia Dortmund has actively tried to sign the striker and had two formal bids of €2 million and €3 million rejected by the Philadelphia Union during the summer. It is understood that the MLS side is seeking a fee exceeding €10 million for the player, who is under contract until 2030.
