Fulham are monitoring Celtic midfielder Arne Engels and face competition from several other clubs. Nottingham Forest have a continuing interest in the 22-year-old, after the Parkhead club rejected their £25 million offer for the Belgian at the end of the last transfer window. Sunderland are also monitoring the player. According to other reports, the relegated West Ham United have also been linked to him. Engels has four caps for Belgium. He joined Celtic in August 2024 from FC Augsburg for a fee of €11 million, and his contract is valid until 2028. In the 2025/2026 Scottish Premiership season, he made 25 appearances, scoring 4 goals and providing 2 assists. His current Transfermarkt market value is €20.00m, and in April 2026, Celtic's asking price was reportedly about €25 million.
