Mikel Arteta's men could only muster a point from a goalless draw against Atalanta BC first up, although they were indebted to David Raya for making an astonishing double save in the second half.
Raya's heroics maintained Arsenal's unbeaten record for the season, though, and the Gunners host the French champions on the back of an engrossing 4-2 win over Leicester City in the Premier League.
Here, Sports Mole rounds up all of Arsenal's latest injury and suspension news ahead of their clash with PSG, who edged out Girona 1-0 in their opening European affair of the season.
Ben White
Status: Major doubt
Type of injury: Knee
Possible return date: October 1 (vs. PSG)
Ben White was forced to play through the pain of a knee injury during the 2-2 draw with Manchester City two weekends ago, but the issue has now flared up again. Having missed the clashes with Bolton Wanderers and Leicester, the right-back is a huge doubt for the Champions League.
Martin Odegaard
Status: Out
Type of injury: Ankle
Possible return date: November 2 (vs. Newcastle United)
Arsenal captain Martin Odegaard was sorely missed in the Gunners' draw with Atalanta BC, and the Norwegian will also sit out the visit of the French champions due to his ankle issue, which should keep him out until November.
Mikel Merino
Status: Out
Type of injury: Shoulder
Possible return date: October 5 (vs. Southampton)
Mikel Merino was initially not expected to be available until after the October international break due to his shoulder fracture, and there is no chance he will be fit for PSG, but Arteta has not ruled out the possibility of the Spaniard making his debut against Southampton next weekend.
Takehiro Tomiyasu
Status: Out
Type of injury: Knee
Possible return date: October 19 (vs. Bournemouth)
Takehiro Tomiyasu is now back in partial training following a pre-season knee injury, although he is slightly behind Merino, so a comeback before the international hiatus is unlikely.
Kieran Tierney
Status: Out
Type of injury: Hamstring
Possible return date: Unknown
Kieran Tierney has been out for a quarter of a year with the hamstring injury he picked up at Euro 2024, and there is still no indication when the 27-year-old might be back in contention for the Gunners.
Oleksandr Zinchenko
Status: Out
Type of injury: Calf
Possible return date: October 27 (vs. Liverpool)
Oleksandr Zinchenko hurt his calf before the derby win over Tottenham Hotspur on September 15, and Arteta has conceded that the Ukrainian still needs another few weeks to get back to full fitness.
