1) Arsenal have to use their midfield brawn
With Joao Neves, Vitinha and Fabian Ruiz, PSG have arguably the most technically gifted midfield in the world.
Luis Enrique’s side can, therefore, play teams off the park simply due to the passing range of their midfielders.
The only way to disrupt their patterns of play is to press them relentlessly, as well as utilising physicality and power to knock them off their stride.
Luckily, Arsenal have players like Declan Rice and (to a lesser extent) Martin Odegaard who can put intense pressure on their opposing numbers. The absence of Thomas Partey is, however, a blow.
