Liverpool are trying to sign Colombia winger Luis Diaz from Porto in the current transfer window.
The deal, if completed, is expected to be worth €45m plus a maximum of €15m in potential bonuses.
The 25-year-old had been linked with a move to Tottenham, who reportedly had a bid of around £38m rejected.
Diaz was Liverpool boss Jurgen Klopp’s first choice for the summer when the asking price would have been €60 million.
Diaz has played against Liverpool twice in the Champions League this season, with Porto losing 5-1 and 2-0 in the group stages of the competition.
He’s scored 20 goals in 37 appearances for club and country this season.
