Gunners scouts have been impressed by the 23-year-old's versatility across the frontline during their visits to monitor Ethan Nwaneri's loan spell at the German club. Beier's ability to play in various positions could be an attractive asset for Arsenal, who are looking to strengthen their attacking options. The move would see Beier potentially join the likes of Gabriel Jesus and Bukayo Saka in the Gunners' front line.
Manchester United have lined up Lens winger Mezian Mesloub as a potential long-term target, with scouts from several top clubs tracking the 16-year-old. Real Madrid are also assessing a move for Manchester United youngster JJ Gabriel, who has indicated his desire to leave Old Trafford.
