Liverpool new signing Sepp Van Den Berg must wait for his debut for the club as FIFA sorts his international clearance.
Paperwork for the 17-year-old, who arrived last month from PEC Zwolle for an initial £1.3million fee, is still being processed by FIFA and until the club receives an official confirmation, he is only allowed to train with the squad.
It means he is unlikely to feature in Sunday's second pre-season friendly at Bradford but will travel to America with the rest of the squad on Tuesday for training and matches against Borussia Dortmund, Sevilla and Sporting Lisbon.
Liverpool already has four established centre-backs in Virgil Van Dijk, Joel Matip, Joe Gomez and Dejan Lovren - who is interesting AC Milan but will only be allowed to leave for offers in excess of £25m - so Van Den Berg has been brought in with one eye on the future.
However, manager Jurgen Klopp has not ruled out the Holland Under-19 defender being involved with the first team this season.
“It depends. I open the door but the boys have to go through still,' Klopp said.
“He is a wonderful player as well, but because of FIFA rules he is not available at the moment, but we have other good players. He thought his future should be here and I thought the same, so now he is here and now let's work together,” Klopp said.
Klopp is also expected to add more youth to the ranks with the acquisition of Fulham youngster Harvey Elliott, PA understands.
