That Arsene Wenger hasn't had all of his players fit and available since the arrival of record signing Mesut Ozil has been a blessing in disguise for the Arsenal boss.
But soon, after the international break, the Frenchman will be forced to make some tough decisions.
Santi Cazorla is set to return from injury - and the Gunners' best player from last season must go straight into the side if Arsenal are to remain on course to challenge for the Premier League title this term.
And then there's Theo Walcott and Alex Oxlade-Chamberlain, who will both be knocking on the door of the Gunners' boss when they come back from their respective injuries.
Fitting them all into the starting line-up is obviously impossible - but Arsenal have enough games over the course of the season for Wenger to convince his stars that rotation will be crucial over the coming months.
That said, who will Wenger deploy in the biggest matches? For those make-or-break Premier League clashes against big-name rivals and Champions League ties in the knockout rounds, the Gunners boss will need to field his best possible XI.
Aaron Ramsey now has to make the team after a sublime start to the season, which means Cazorla may need to play from a wider position.
Meanwhile, Mathieu Flamini has made such a big impact on his return to the Emirates Stadium that he will probably be given the nod as the team's number one defensive midfielder ahead of Mikel Arteta.
That leaves Jack Wilshere to occupy the other midfield role as part of that central trio.
Ozil loves to float around the advanced positions and often finds himself on the right-hand touchline, so the £42.4m man could start in the wide-right position ahead of Theo Walcott against teams who know how to defend.
And Olivier Giroud takes the striker spot - at least until Arsenal sign Karim Benzema in January...
Arsenal's best XI:
Goalkeeper: Wojciech Szczesny
Left-back: Kieran Gibbs
Centre-back: Laurent Koscielny
Centre-back: Per Mertesacker
Right-back: Bacary Sagna
Defensive midfield: Mathieu Flamini
Central midfield: Jack Wilshere
Central midfield: Aaron Ramsey
Left-wing: Santi Cazorla
Right-wing: Mesut Ozil
Striker: Olivier Giroud
Bench: Emiliano Viviano, Thomas Vermaelen, Nacho Monreal, Mikel Arteta, Alex Oxlade-Chamberlain, Theo Walcott, Nicklas Bendtner.
If you was Arsene Wenger - what would you do?
