The 23-year-old has become an important figure in Serie A side’s defence, but reports suggest he is close to appointing a new high-profile agency to manage his career, a move that has intensified transfer speculation.
According to reports in Italy, several leading sports agencies are competing to represent Bisseck, with Giovanni Branchini currently leading the race.
The situation has alerted clubs in both the Premier League and Bundesliga, with Bayern Munich closely monitoring the German centre-back’s progress.
Despite growing interest, Inter Milan remain determined to keep Bisseck in Milan.
The defender is also understood to be happy at San Siro, though interest from Europe’s elite could still test the Black and Blues’ resolve in future transfer windows.
