However, a mostly inexperienced group capitulated thereafter as Alexandre Lacazette (2), Rob Holding and Eddie Nketiah all netted to make it an emphatic victory for Emery over his previous employers.
I will tell you once it's done. It will also be nice for me to meet my friends who I worked with at Paris Saint-Germain. "Aaron Ramsey also captained us in a friendly and I am maybe thinking another one or two players can take responsibility for every player in the team".
Most of PSG's senior squad remains absent due to their World Cup exploits, whereas Arsenal were almost at full strength and a prickly Tuchel wasted no time in pointing to that disparity.
"He will be even better at Arsenal because Arsenal are always trying to control the game with short passes and moving together up the pitch, so it's a flawless place for him to develop his vision of the game and I think he's going to have success there".
"We saw this with Chelsea; they had no European games three years ago and became champions".
On what he has seen from his squad this pre-season, the head coach said that he is more content seeing his players working on their fitness rather than worrying about results.
Although they start the domestic campaign against a side they are fully expected to beat, Tuchel added that such teams relished facing the bigger sides soon after a World Cup. It's about getting the players to rest.
"We want to find a space for him and the other players where they can use their qualities through good positioning".
Although PSG's starting XI was packed with young players, they enjoyed a far greater start and nearly made the most of their early pressure - Azzeddine Toufiqui sending a curling left-footed effort just wide from 20 yards after a brilliant marauding run from Adrien Rabiot.
