This summer Liverpool, Bayern Munich, and now Manchester United are set to battle it out for Dortmund midfielder Christian Pulisic.
The American has seen his name arise more and more frequently in transfer debates. Having shone in the Bundesliga, Pulisic, valued at £40m, would be a valuable addition to any top side.
Given Klopp's links with Dortmund, Liverpool remain the favourites to sign the promising young American.
However, his current club is not keen on letting him go, with Dortmund's sporting director Michael Zorc stating that the side are 'planning with him well beyond the summer.'
