Top Premier League teams are appearing in the International Champions Cup - but which players haven't been taken on tour?
Manchester United, Arsenal, Chelsea, Tottenham and Manchester City's are all taking part in the competition as they get ready for the new campaign.
But their touring squad lists have made for interesting reading - as much for who has been left at home, as who has travelled with the team.
The International Champions Cup, which takes place in USA, China and Singapore, has given those clubs - along with elite outfits from Spain, Italy, Germany and France - the opportunity to play high-profile friendlies abroad.
But with the transfer window in full swing, clubs appear to have been loath to take players potentially on their way out on the plane. Injuries have also been a cause for some key figures to stay at home, while a selection of international stars have been given extra time off.
Here, we take a look at the touring parties for Manchester United, Arsenal, Chelsea, Tottenham and Manchester City, who has been left behind and why…
Jose Mourinho has taken 27 players to the United States for Manchester United's games against LA Galaxy, Real Salt Lake, Manchester City, Real Madrid and Barcelona in between training sessions.
Among the group are youngsters Scott McTominay and Demetri Mitchell but Cameron Borthwick-Jackson and Guillermo Varela - both linked with moves out of Old Trafford - have not travelled.
James Wilson and rising star Angel Gomes were also left out and have instead joined the U23s and U18s on their pre-season trip to Austria.
Full squad: David De Gea, Sergio Romero, Joel Pereira, Antonio Valencia, Matteo Darmian, Timothy Fosu-Mensah, Eric Bailly, Daley Blind, Phil Jones, Chris Smalling, Victor Lindelof, Axel Tuanzebe, Marcos Rojo, Luke Shaw, Demetri Mitchell, Ashley Young, Michael Carrick, Marouane Fellaini, Ander Herrera, Scott McTominay, Paul Pogba, Jesse Lingard, Henrikh Mkhitaryan, Juan Mata, Andreas Pereira, Anthony Martial, Marcus Rashford
US tour fixtures: July 15: LA Galaxy (won 5-2), July 17: Real Salt Lake (won 2-1), July 20: Man City, July 23: Real Madrid, July 26: Barcelona.
Arsenal have flown 25 players to the southern hemisphere, however, Arsene Wenger - whose squad visits Australia and China - has left a number of familiar faces at home.
Lucas Perez, Mathieu Debuchy, Kieran Gibbs and Carl Jenkinson were also absent from the flight which took Arsenal's selected players down under, with those four players linked with moves out of the club. Joel Campbell, meanwhile, is at the 2017 Gold Cup with Costa Rica.
Chuba Akpom, 21, and Jeff Reine-Adelaide, 19, also missed out, which suggests their first-team opportunities could be limited this term, with loan moves a possibility for the developing talents.
Full squad: Petr Cech, Emi Martinez, David Ospina, Krystian Bielik, Cohen Bramall, Francis Coquelin, Mohamed Elneny, Olivier Giroud, Alex Iwobi, Sead Kolasinac, Laurent Koscielny, Alexandre Lacazette, Ainsley Maitland-Niles, Donyell Malen, Per Mertesacker, Nacho Monreal, Reiss Nelson, Eddie Nketiah, Alex Oxlade-Chamberlain, Mesut Ozil, Aaron Ramsey, Theo Walcott, Danny Welbeck, Joe Willock, Granit Xhaka
Australia and China tour fixtures: July 13: Sydney FC (won 2-0), July 15: Sydney Wanderers (won 3-1), July 19: Bayern Munich (1-1; won 3-2 on pens), July 22: Chelsea
Diego Costa, Nemanja Matic and Kurt Zouma have all been left out of Chelsea's 25-man squad for their pre-season tour of China as speculation about their futures continues.
Eden Hazard has also been left behind while he continues his recovery from ankle surgery but Loic Remy is included in the group even though he is expected to leave Stamford Bridge this summer.
New signing Willy Caballero has joined Antonio Conte's squad on their trip to the Far East, while fellow recruit Antonio Rudiger will link up with his new team-mates in Singapore.
Full squad: Thibaut Courtois, Willy Caballero, Eduardo, Marcin Bulka, Cesar Azpilicueta, Gary Cahill, David Luiz, Andreas Christensen, Tomas Kalas, Jake Clarke-Salter, Fikayo Tomori, Marcos Alonso, Victor Moses, Cesc Fabregas, N'Golo Kante, Mario Pasalic, Lewis Baker, Kyle Scott, Pedro, Willian, Kenedy, Charly Musonda Jr, Jeremie Boga, Michy Batshuayi, Loic Remy.
China and Singapore tour fixtures: July 22: Arsenal, July 25: Bayern Munich, July 29: Inter Milan
Tottenham are without four first-team players for their three pre-season matches in the United States, with Heung-Min Son among them as he recovers from a broken arm.
Erik Lamela (hip), Danny Rose (knee) and Moussa Sissoko (virus) have also remained in London and with no new signings so far, that means a number of young players are in the travelling party.
With Kyle Walker having moved on to Manchester City, Kieran Trippier is in the pool as he sets about trying to establish himself as Tottenham's new regular right-back after signing a new five-year contract.
Full squad: Toby Alderweireld, Dele Alli, Brandon Austin, Jaden Brown, Cameron Carter-Vickers, Ben Davies, Mousa Dembele, Eric Dier, Jon Dinzeyi, Christian Eriksen, Anthony Georgiou, Vincent Janssen, Harry Kane, Hugo Lloris, Will Miller, Georges-Kevin Nkoudou, Tashan Oakley-Boothe, Josh Onomah, Kieran Trippier, Jan Vertonghen, Michel Vorm,
Kyle Walker-Peters, Victor Wanyama, Alfie Whiteman, Kevin Wimmer, Harry Winks.
US tour: July 23: PSG, July 26: Roma, July 29: Man City
City have not released an official squad list but fans will be reassured Sergio Aguero - linked with a move to Chelsea - was in their group when it travelled to America.
New signings Kyle Walker, Ederson and Bernardo Silva were also on the flight and although Leroy Sane and Yaya Toure were not, that was for logistical reasons and they later joined up with Pep Guardiola's squad.
Samir Nasri, who spent last season on loan to Sevilla, joined City on their journey to the States as did Patrick Roberts, who has just finished an 18-month loan spell at Celtic.
Gabriel Jesus, David Silva, Raheem Sterling and Kevin De Bruyne were among the other big names bound for Houston prior to their first game against Manchester United.
US tour fixtures: July 20: Manchester United, July 26: Real Madrid, July 29: Tottenham
