Mikel Arteta called for his side to produce "something special" in next week's Champions League decider against Paris Saint-Germain after a 1-0 defeat in Tuesday's semi-final first leg.
Arteta pointed to "fine margins" as the difference between the two sides at the Emirates, as Ousmane Dembele's fourth-minute strike put PSG in pole position to reach the final in Munich on May 31.
