Arsenal tactics v PSG: Odegaard, Vitinha and four ways Arteta can mastermind Paris win

Mikel Arteta says Arsenal will use “rage, anger, frustration” and “a bad feeling in the tummy” to try and overturn the 1-0 Champions League semi-final first-leg deficit against Paris St-Germain.

For supporters travelling to Paris on Wednesday, the scene of Arsenal’s 2006 Champions League final defeat, the stomach churns.

Arsenal have not scored in any of their past seven semi-final matches in all competitions (losing five and drawing two).

But PSG have their own Champions League ghosts, their own archive of meltdowns. The tie still hangs in the balance.

Thomas Partey’s return to Arsenal’s midfield could be decisive, as could Ousmane Dembele’s fitness after only training since Monday.

Then there is the tactical battle, won by Luis Enrique in the first leg but, thanks to Mikel Arteta’s mid-game tweaks, perhaps set up to swing in Arsenal’s favour.

Get past the nerves and the historic trauma, and Arsenal supporters have reason to feel optimistic. Four reasons, to be exact.
