Hull City have engaged in initial discussions with the agent of Marvin Keller, a 23-year-old Swiss goalkeeper for Young Boys. Keller is being considered by Hull City as they seek reinforcements for the upcoming transfer window following their promotion to the Premier League. The goalkeeper's contract in Switzerland runs until June 2028. Hull City may face competition from Brighton and Hove Albion and Ajax for the player. It is thought that Hull could offer Keller more game time than Brighton, whose first-choice keeper is Bart Verbruggen, and this could make a transfer to Hull City an attractive option for the player. Keller joined Young Boys in February 2023, made 38 appearances in the 2025/2026 Super League season, and has one cap for Switzerland. His current market value is €6.00m, according to Transfermarkt.
