The Reds are facing a battle of their own to keep Brazil international Philippe Coutinho amid interest from La Liga giants Barcelona in their star number 10.
Pulisic has been named as a potential successor to Coutinho in the Liverpool team should the Reds eventually cave and sell the South American to the Camp Nou outfit.
Liverpool have previously been linked with a move to sign the American teenager but Borussia Dortmund have been reluctant to sell the promising attacker.
The United States teenager scored three times and made six assists in 29 appearances in Bundesliga last season, while he netted once and made two goals in the Champions League.
Former Liverpool defender Nicol reckons former Dortmund manager Klopp gives the Reds a slight advantage in their pursuit of the exciting Bundesliga teenager.
“I’m not going to sit here and try and argue black’s white. The fact is Dortmund were in the Champions League last season,” Nicol told ESPN FC.
“Dortmund were in the final more recently than Liverpool so it is kind of hard to turn around and say they are lower than Liverpool.
“But I would suggest that the Jurgen Klopp factor at Liverpool, because clearly he knew all about Pulisic, I’m sure he had some sort of relationship with Pulisic.
“That would be the one thing other than money that would maybe make Pulisic go from Dortmund to Liverpool – that Klopp connection.
“If Klopp’s not at Liverpool it’s got no chance of happening.”
Klopp was still head coach at Dortmund when the German club signed Pulisic in February 2015.
The German coach was confirmed as Brendan Rodgers’ successor in October 2015 and missed out on the chance to coach the teenager in the Dortmund first-team.
