Defender Kevin Danso is being chased by four European clubs this summer.
The 25-year-old spent the 2019/20 season at Premier League side, Southampton on loan.
However, with his contract with his parent club, Augsburg runs until 2024, Danso's loan deal with the English was not extended.
HSV and Fortuna Düsseldorf are showing interest - with FC Watford and Nottingham Forest there is also competition from England.
The past season did not go according to plan for Danso on the island, it was only enough for six league appearances with the Saints.
