Haller had already spent the second half of last season on loan at Utrecht and was able to improve his form. In 18 competitive matches, the 31-year-old scored six goals and provided another assist. Dortmund will no longer receive a transfer fee for Haller, who was signed from Ajax for €31 million (£27m/$36m) in 2022 and is one of the club's top earners with a reported €10m per year. On the contrary, Bild states that Dortmund still have to pay Haller a severance package of around €2m.
