Liverpool have accepted a bid worth up to £3.5 million ($4.5m) from Rosenborg for midfielder Pedro Chirivella.
The Spaniard has featured regularly during the Reds’ pre-season campaign, and played in the 4-1 win over Manchester United in Michigan on Saturday.
But having returned to Merseyside with the rest of Jurgen Klopp’s squad, the 21-year-old is now set to travel to Norway to finalise his transfer.
The deal should be done before Rosenborg take on Celtic in their Champions League qualifier on Wednesday.
Liverpool will receive £2.4m ($3.1m) up front with the rest in performance-related bonuses.
