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.
