Mikel Arteta's men are seeking to improve on a dismal eighth-placed finish last term and will navigate a campaign without European football for the first time in 25 years.
The Gunners claimed a pair of 4-1 training ground victories over Watford and Millwall in pre-season, but three of their more high-profile clashes against Hibernian, Chelsea and Tottenham Hotspur all ended in defeat.
Thomas Partey
Arsenal injury, suspension list vs. Brentford
Status: Out
Type of injury: Ankle
Possible return date: September 11 (vs. Norwich City)
The injury-hit Thomas Partey re-entered the Arsenal treatment room with an ankle injury sustained in their pre-season defeat to Chelsea. The former Atletico Madrid man is set to spend the rest of August recovering from the issue, meaning that he will miss crunch clashes with Chelsea and Manchester City.
Eddie Nketiah
Arsenal injury, suspension list vs. Brentford
Status: Out
Type of injury: Ankle
Possible return date: September 11 (vs. Norwich City)
Like Partey, Eddie Nketiah - who could still leave during the current transfer window - also injured his ankle during the Mind Series clash with the Blues and will be keeping his teammate company in the medical room for the next few weeks.
Gabriel Magalhaes
Arsenal injury, suspension list vs. Brentford
Status: Out
Type of injury: Knee
Possible return date: Unknown
Gabriel Magalhaes sustained a knee injury over the summer and was forced to withdraw from Brazil's gold medal-winning Olympic team. The 23-year-old is recovering at Arsenal's training base and will return to action 'in the forthcoming weeks' according to the Gunners' latest medical update.
Rob Holding
Arsenal injury, suspension list vs. Brentford
Status: Minor doubt
Type of injury: Fitness
Possible return date: August 13 (vs. Brentford)
Rob Holding did not take part in Arsenal's pre-season defeat to Tottenham due to a lack of fitness, but he is fighting an uphill battle to displace new arrival Ben White in the team either way.
ARSENAL'S SUSPENSION LIST
Arsenal have no players suspended for Friday's trip to Brentford.
