The Gunners hammered Benfica 5-2 on Before going down 2-1 to Sevilla 24 hours later, securing an Emirates Cup win thanks to a points system which rewards goal-scoring. Ultimately, the results and trophy win count for little, though - Wenger will be far more focused on his side's performances.
Here, we take a look at what lessons he can take from the pre-season tournament…
'Powerful' is the word which springs to mind when assessing Sead Kolasinac - and his performance at left wing-back against Benfica reflected his burly physique. The summer signing bullied Pizzi out of possession before crossing for Theo Walcott to score Arsenal's opener, and repeatedly surged forwards with the ball.
But there were moments of cuteness too. As well as the precise, clipped cross for Walcott, Kolasinac played a neat wall pass for Francis Coquelin to tee up the England forward for his second, before feeding Olivier Giroud in the box in the build-up to Alex Iwobi adding Arsenal's fifth.
Wenger was left impressed. "I think he has gone, in pre-season, from strength to strength," said the Arsenal boss. "He started a bit nervous, but every single week he moved his level up. The first two goals came from him. He looks powerful and the timing of his availability going forward was very good."
