Liverpool are in talks with Hull City over the signing of defender Andrew Robertson, according to Sky sources.
The Scotland international left-back has flown home from the club's pre-season tour in Portugal and another source claims a fee that could rise to £10m has been agreed.
Robertson made 39 appearances in all competitions last season as Hull were relegated from the Premier League.
The 23-year-old started his career at Queen's Park before moving to Dundee United. He joined Hull in July 2014, making his debut in a 1-0 win over QPR.
Liverpool have already signed Mohamed Salah and Dominic Solanke this summer.
