Mikel Arteta’s side head into this second leg boasting three away goals and good form, but this Arsenal side have shown on more than one occasion this season that they have a defensive howler in them.
Arsenal are heavy favourites to reach the last eight of the competition, but Arteta will want to see a professional performance from his players – especially given that winning the Europa League represents the Gunners’ best chance of qualifying for the Champions eague next season.
