Paderborn reject a reported £4m bid from Celtic for midfielder Baur, according to gossip reports cited by multiple outlets. Both accounts say the German club turns down the offer, though they frame the development as part of an ongoing and possibly evolving transfer discussion rather than a fully confirmed deal. The reports also describe uncertainty around related interest, including claims about another player linked to Celtic’s potential recruitment plans. While the central point in both sources is that Celtic’s bid for Baur is refused, the outlets differ or remain unclear on broader details such as whether other offers are being considered, whether negotiations continue, or how other names connected to the proposed move fit into the same situation. Overall, the information is presented as unverified transfer talk, with the key shared update being Paderborn’s refusal of Celtic’s £4m offer for Baur and the presence of conflicting reporting around associated player movement.
