Jay-Jay Okocha's nephew netted his first Arsenal goal and got plenty of game time at this year's Emirate Cup. Wenger, meanwhile, confirmed that the 19-year-old won't go out on loan next term - and the north London side's striker shortage suggests he could well have a route into the first team in future.
Iwobi's performance during the 6-0 win over Lyon had fans calling for him to be given a Capital One Cup run next season. He is certainly one to watch.
Gunners fans were even more taken aback, however, by 17-year-old Reine-Adelaide's displays for Wenger's men during the Emirates Cup. The teenager has seemingly come from nowhere and drew great praise from his manager.
Against Wolfsburg, in particular, Reine-Adelaide impressed, registering the assist for Theo Walcott's winner. Just like Iwobi, the youngster possesses talent in abundance and it'll be very intriguing indeed to see how he does long term.
One of Arsenal's established stars, Ozil had Wenger purring after the 6-0 against Lyon, with the Frenchman declaring that the German has won over all Gunners fans. Consistency remains the issue for Ozil over the course of a full campaign but he was up to his old tricks again over the weekend, showing flair, audacity and, of course, his trademark deadly eye for a pass.
Last but by far not least, former Chelsea goalkeeper Cech gave Arsenal supporters something they've been waiting for for years: a shot stopper with the utmost experience and authority.
During his Emirates Cup minutes, the 33-year-old made important saves but, most importantly, communicated with his back line and told them what was what. He isn't enough to win Arsenal the Premier League alone by a long shot - but Cech can quite easily establish himself as one of the Gunners' best signings in years, if not ever.
