BBC Sport told in July how Liverpool was considering a deal for it up to £ 130 meters.
Newcastle has said that it is not for sale in this summer, but it has not prevented the side of the Arne slot from taking a big interest.
The Premier League Champion created an approach to Newcastle last month before making an official bidding.
The boss slot has already added several additions to its squad during the heavy summer of the Enfield Club.
He has signed Florian Vartz, Hugo Activa, Milos Kercase, Jeremy Fimpong, Georgi Mamdashwili and Armin Packsi for a combined clan of approximately £ 265M without add-on.
Meanwhile, the departure of Luis Diaz, Jarel Quansa, Cammhin Kelher and Trent Alexander-Aneold resumed the initial £ 115m.
