Brighton face a battle to keep hold of youngster Aaron Connolly.
Sky Sports says Hoffenheim are tracking Connolly, as the German club continue their model of scouting Premier League prospects not currently getting first-team football.
Connolly - a Republic of Ireland U19 international - has scored nine goals in 10 league games for Brighton's U23s this season and five more for them in just three outings in the EFL Trophy.
The 18-year-old is understood to be stalling on the offer of a new contract, and the Seagulls are considering letting him out on loan in the January transfer window.
