Liverpool are growing increasingly concerned Rhian Brewster could leave the club this summer to go to the Bundesliga.
The England Under-17 international, who helped his country to World Cup glory back in October, is yet to sign a professional contract at Anfield.

Reece Oxford, Ademola Lookman and Mandela Egbo have all found first team opportunities playing for their respective clubs in the Bundelsiga.
