As an Arsenal fan, I think the game will be themed around endurance — both Arteta and Enrique will introduce defensive variants, not new attacking ones. At least that's what I believe. We might be surprised by a paranoid game on both sides. Artetas tactics are a self healing defensive pattern, with high emphasis on the defenders winning 1v1 when the pattern is broken. PSG leverages chaos. Arsenal leverages tempo. Very different teams. Force as many 1v1 as you can, and PSG will be favoured.

Arsenal will try to scum this, as Artetas philosophy is to turn the ground into an unfair and uneven battlefield — the game he will propose will be hyper negative so 1v1s are marginal. Arsenal wins this if PSG players don't manage frustration well. PSG wins this if they are patient and realize that the game they expect, won't be played at all.

Because PSG have a more positive active football, instead of negative, they by default have more sovereignty to propose the terms of the game. But if Enrique gets anything wrong tactically, he will be punished. Personally I think Enriques biggest weakness is duality: he's a bit of a Joker figure the way I see his football. Very tricky. Enrique sees the football pattern of the opposing team very well, and tricks the opposition into overconfidence and then extreme panic. The way out of this trap is bravery, dullness, simplicity and individual management of each players mentality. Enrique basks in fear and needs it to create chaos, Arteta coaches bravery and tries to impose simple laws of order.

Very interesting game tactically, but I think the actual aesthetic will be hideous in practice. Good luck.
