Liverpool have threatened Borussia Monchengladbach over their interest in Rhian Brewster.

The Telegraph says Liverpool believe delays from Brewster over signing a new contract stem from Gladbach's interest.

The Reds have told Gladbach to back off and threatened to report them over an illegal approach.

Liverpool have triggered the third year of Brewster's Academy scholarship which means that no club is currently allowed to approach him.

Anyone doing so at this stage will run the risk of being reported for tapping-up the youngster.
