Liverpool's England internationals all returned to training as the first-team squad underwent a light session hours after touching down in the United States for a 10-day pre-season tour.
After the Reds beat Huddersfield Town 2-0 at the John Smith's Stadium in their fourth and final home soil friendly, the first-team squad took an 11-hour flight to North America in the early hours of Thursday morning.
Based in California's Silicon Valley for the next week, Jürgen Klopp oversaw a session at Stanford University later the same day as he welcomed back Daniel Sturridge, Jordan Henderson, Adam Lallana, James Milner and Nathaniel Clyne - who were all already in the US.
Ahead of fixtures with Chelsea, AC Milan and AS Roma - the former two coming in the International Champions Cup - all of the England quintet involved at Euro 2016 trained with their teammates, including their five summer signings so far.
Klopp expecting full contingent together by next Tuesday
Klopp will soon have his full squad at his disposal, with the rest of their internationals due to return over the next few days - with Emre Can of Germany the latest to be expected back by next Tuesday.
Having spoken about taking just two youngsters across the Atlantic, goalkeeper Shamal George - who made his first-team debut as a makeshift striker at Huddersfield - has filled in for Adam Bogdan, who has gone out on loan to Wigan Athletic.
He's joined by midfielders Trent Alexander-Arnold and Ovie Ejaria, the only other representatives of the club's Academy.
Kevin Stewart, Connor Randall, Cameron Brannagan and Brad Smith have all travelled having been promoted to the first-team on a permanent basis under Klopp.
But winger Ryan Kent and 16-year-old striker Ben Woodburn have remained on Merseyside in order to seal a loan for the coming campaign and due to school commitments respectively.
It will be somewhat of a disappointment to both, with the two forwards among the most impressive pre-season performers thus far.
Woodburn sparked a frenzy on social media netting goals in back-to-back games and combining his output with effective displays, while Kent added an explosive spark out wide and was one of the stand-outs in their four fixtures.
Also left behind in Liverpool are outcast striker Mario Balotelli, who has been told his time is up at the club, Tiago Ilori who is training for the Olympic Games with Portugal Under-23s, and injured Academy midfielder Pedro Chirivella.
But perhaps the most high-profile absentee is Jon Flanagan, who has stayed on L4 as he decides whether to go on a season-long loan to Burnley.
Elsewhere, Lucas Leiva, Mamadou Sakho and Joe Gomez were all included in the squad that flew to the States despite injury problems.
Lazar Markovic and Andre Wisdom, both of whom appear unlikely to demand a place in Klopp's squad for the 2016-17 season, are with the Reds in Pato Alto as they look to prove otherwise.
Number of Reds' tour status unknown with futures uncertain
Competition for places is sure to heat up over the next few weeks, Belgian duo Simon Mignolet and Divock Origi due back before Liverpool's clash with Chelsea in Pasadena next Wednesday.
Christian Benteke is also expected back at the same time as his compatriots, although it is not yet known whether he will travel to the United States.
Crystal Palace are currently unwilling to meet Liverpool's asking price for the out-of-favour striker having offered £31.5 million for the frontman earlier this month, only £27.5 million of which was up-front.
The Reds are looking to bank at least a guaranteed fee of £30 million and Palace have yet to come up with an improved offer, leaving the potential transfer at a standstill.
With his future also in doubt, Joe Allen is likely to have left the club by the time he would be expected to return from a summer break.
Subject of a £13 million offer from Stoke City, which has been accepted, the Welsh midfielder will now enter discussions with the Potters over a move away from Anfield.
But the Liverpool squad will be soon boosted by the arrival of Georginio Wijnaldum, who is due to undergo a medical at the club's Melwood training ground ahead of a £25 million switch from Newcastle United.
Expected to put pen-to-paper on a five-year deal with the Reds, Wijnaldum will travel to the US the same day with the potential of making his first appearance against Chelsea at the 92,500-seater Rose Bowl.
Trialist goalkeeper Alex Manninger, who has been training with the club over the last few weeks with a view to signing a one-year contract as third-choice back-up, is also with the squad.
