The Reds were unsuccessful in their attempts to sign Pulisic in 2016, with Dortmund turning down an £11 million bid before the teenager signed a new long-term contract the following year.
Pulisic has gone on to establish himself as the focal point of the United States national team, and a first-team regular at the Westfalenstadion.
This has seen speculation over a move to Anfield fade, but with Philippe Coutinho leaving for Barcelona this month an as-yet-unnamed replacement has been mooted.
And speaking as part of The Totally Football Show on Monday, German football expert Rafa Honigstein, who has connections with both Dortmund and Liverpool, hinted at another bid for Pulisic.
However, he also believes Jurgen Klopp‘s former club will not be willing to sell.
