Premier League rivals are chasing Aston Villa striker Andi Weimann.
With just a year left on his contract at the end of the season, Weimann, 21, could have his pick of top teams this summer - whether Villa survive or not in their drop-zone battle.
The Austria star wants to see what happens in the relegation scrap before committing to the Villains, even though the club are desperate for him to stay.
Kop boss Brendan Rodgers is a confirmed admirer of the forward and will make a move after Fabio Borini's lack of impact at Anfield.
North London rivals Arsene Wenger and Andre Villas-Boas both like Weimann, but the keen interest from Dortmund could blow them out of contention.
