Liverpool have entered into advanced negotiations with Bayer Leverkusen over a deal for Florian Wirtz.
It is understood the Premier League champions have submitted a second, improved bid for the Germany winger.
Liverpool's latest offer for the 22-year-old is about £109m, including add-ons.
Wirtz is a key target for the Merseyside club and has made his wishes clear about wanting to join Liverpool before next season.
BBC Sport revealed earlier this month that Manchester City are no longer in the running for the player, citing costs attached to the transfer as a key factor.
