Borussia Dortmund are concerned over the growing interest in teenage prospect Charles Herrmann.
The left-sided midfielder, now just turned 18, comes off contract at Dortmund at the end of the season.
Sky Deutschland says Brighton are showing serious interest in Hermann, who won the U17 World Cup last year with Germany.
Initial discussions have taken place about extending the contract between the player's camp and BVB.
Along with Brighton, LaLiga interest has also arrived.
