According to reports in the German media, suggested the Reds are determined on summer raid for Sead Kolasinac, Max Meyer and Leon Goretzka.
However, Heidel has moved to quickly to stop such rumor and says he would know if Liverpool’s interest was genuine due to his relationship with the Reds' Chief Jurgen Klopp.
“I happen to know some guy in Liverpool quite well,” Heidel told RevierSport.
“Jurgen and I have such a good relationship that I have always been in the loop on everything. This time I do not know anything. That means the English media knows nothing either.
“I do not know who the Liverpool scouts are monitoring. Not even Klopp always knows what they are up to.”
Liverpool previously swooped Schalke after bringing in Joel Matip on a free in 2016, and while Kolasinac is also available for nothing this summer, the Bosnian full-back player looks to be destined for Arsenal.
The Reds’ interest in Meyer, however, is not a new story.
The young forward, who has also been connected with Tottenham has recently revealed he'd like to try his luck in England.
Both Meyer, 21, and Goretzka, 22, have contracts until June 2018.
