Similarly, PSG will look to disrupt Arsenal’s possessional dominance by pressing high, likely in a man-to-man fashion. The intensity from players like Dembele, Khvicha Kvaratskhelia and Desire Doue up top will look to force Arsenal into early turnovers and big chances of their own, or long balls, betting on the likes of Marquinhos and Willian Pacho to win aerial duels.
With aerially-dominant Mikel Merino out and Kai Havertz returning to full fitness, if it is Gyokeres set to battle with the PSG defenders, making the ball stick might be a tougher ask for Arsenal.
Against Bayern, PSG often defended in a man-to-man fashion. If this happens against Arsenal, the Gunners may look for runners in behind after pulling central defenders deeper through attacking movements of their own.
Alternatively, PSG may set up to defend deeper if Arsenal are able to dominate the ball like they did last season.
In those games, Gianluigi Donnarumma was in goal, and his individual brilliance saved PSG on a number of occasions. With Matvey Safonov in goal for PSG this season, defending deep suddenly becomes a riskier option.
