Departures are the priority at the BayArena before Tuesday's deadline, with decisions on Axel Tape's proposed loan move to Levante and Arthur's switch to Hamburg SV both expected imminently.
Belocian's situation remains less settled, though the 21-year-old could yet stay in the Bundesliga if a loan is arranged. According to Bild, four top-flight clubs are considering a move for the centre-back, whom Leverkusen would be happy to loan out in search of more regular game time.
Werder Bremen have already been known admirers, and the tabloid has now added Augsburg to the list of interested parties, while French Champions League side RC Lens are also in the frame.
Belocian has been on Leverkusen's books since 2024, though he spent the second half of last season on loan at VfL Wolfsburg, where he made 14 Bundesliga starts and provided an assist during the club's fight against relegation, including in the play-offs.
Despite that experience, the Caribbean-born Frenchman has managed only 20 competitive appearances for Leverkusen in total since his move from Rennes.
Lens are believed to view Belocian as a possible alternative to RB Leipzig's El Chadaille Bitshiabu, another centre-back on their radar, and are working on a loan structure that could make them serious competition for Werder Bremen. The Frenchman himself is understood to be open to a return to his home country, which could give Lens an edge in the race, though nothing has been finalised and Leverkusen remain open to either a fresh loan or a permanent sale depending on what emerges before the window closes.
Belocian is not the only defender Werder have been linked with at Leverkusen, with the Bremen-aligned outlet DeichStube also connecting the club to right-footed defender Tim Oermann, suggesting the Bundesliga side could be shopping for more than one option to strengthen their backline before deadline day.
Belocian's versatility, having featured both at centre-back and in a deeper midfield role during his career, adds to his appeal for suitors who may be seeking a defender capable of covering more than one position as squads are finalised for the season ahead.
