Eddie Nketiah scored the winning goal for Arsenal
Arsenal took the lead through debutant Marquinhos converting from Eddie Nketiah's cutback after 16 minutes.
But Zurich equalised before half-time courtesy of Mirlind Kryeziu's penalty after Nketiah fouled Ola Selnaes.
Nketiah restored Arsenal's lead in the second half, heading in at the far post from Marquinho's cross. Mikel Arteta's side face PSV Eindhoven in their second Europa League game next Thursday.
