Liverpool boss Jurgen Klopp has hinted Curtis Jones, Nathaniel Phillips and Ben Woodburn could be allowed to leave the club on loan.
The trio travelled to the US with the first-team but participate in Sunday's friendly with Napoli and won't be involved in this week's training camp in Evian.
Klopp told the club's website: "We have players coming back now and so we decided that they don't train with us, because of the number of players we have.
"We don't need that number of players and they can have the pre-season now with the U23s, having games and sessions.
"We have 23 or 24 plus goalies in Evian; it would mean these three plus Ryan Kent [absent with illness] involved would be 28 or 29 and that's not necessary. We don't need that big number, that's why we decided that."
