It's the start of pre-season training for Arsenal's senior players today, although not every member of the first-team squad is expected to be involved.
Due to the World Cup and Africa Cup of Nations qualifiers, UEFA Nations League and friendly matches that took place shortly after the 2021/22 season ended only reaching their conclusion a fortnight ago, it means there will be a lack of senior members present for the Gunners at London Colney this week.
Therefore the likes of Aaron Ramsdale, William Saliba, Martin Odegaard, Bukayo Saka, Granit Xhaka, Gabriel Martinelli, Nuno Tavares and Emile Smith Rowe aren't expected to be present for the first day of pre-season training as they've all been given extra time off following their international commitments.

New signings Marquinhos and Fabio Vieira are unlikely to be present either as despite being unveiled as Arsenal players their respective moves from Sao Paulo and Porto won't officially be completed until July 1 as that's when the international transfer window opens.
The same applies to Matt Turner - whose initial £4.5m transfer which could rise to £7.5m - from Major League Soccer (MLS) side New England Revolution was finally confirmed on Monday morning as the club announced the plan is for him to join up with his new teammates next month.
Although if the Gunners were to complete the signings of Gabriel Jesus and Raphinha before Friday the Brazilian pair can immediately take part in pre-season training as deals between Premier League clubs have been permitted since the transfer window opened on June 9.
Of course, Mikel Arteta can call up a number of academy players such as Charlie Patino, Miguel Azeez and Omari Hutchinson to boost the numbers in training. In terms of first-team players that are likely to be present for the first day, it will be those who weren't called up for international duty.
This will include Bernd Leno and Ainsley Maitland-Niles despite the pair being linked with moves to newly-promoted Fulham and Nottingham Forest respectively as they would have needed to have sealed transfers away by now in order to not be available.
Arthur Okonkwo, Rob Holding, Cedric Soares, Benjamin White, Thomas Partey, Albert Sambi Lokonga and Eddie Nketiah are the other senior players who have been on holiday since the final game of last season. Meanwhile, Benjamin White should be ready for the start of pre-season provided he has recovered from injury that saw him pulling out of the England squad at the beginning of the month.
Fellow centre-back Gabriel Magalhaes, right-back Takehiro Tomiyasu and winger Nicolas Pepe could also be in the same boat as White, considering they were called up by Brazil, Japan and Ivory Coast, respectively, earlier in the month but also didn't feature.
In a huge boost for Arsenal and Arteta, Kieran Tierney - who missed the final two months of last season - has already revealed he is on course to be available after being sidelined since April with a knee injury: "It's tough working full days in the gym on your own," he revealed. "But you've got to keep on pushing yourself. There's no point feeling sorry for yourself. I don't look for or expect sympathy from anyone. At the end of the day, I'm lucky to be a footballer — and I never take anything for granted. I'm a nightmare for the physios. I'm always on at them to get me back quicker.
"And I'm a terrible spectator. Not being able to do anything to help the team. I hate it. My target is to be back for the end of June and the start of pre-season at Arsenal. I'm on course for that. My rehab's going well."
Along with Tierney, a number of recalled loanees such as Hector Bellerin, Pablo Mari, and Reiss Nelson could also be present as they haven't earned permanent moves away as of yet.
