Arsenal travel to Spain on Thursday looking to book themselves a spot in this season's Europa League final, and potentially, a spot in next year's Champions League.
With a 3-1 lead from the first leg, Unai Emery and his players will have to navigate a tricky away tie against a team who scored six goals in their La Liga game at the weekend.
The Gunners' away from this season has been poor, and this should worry Emery and Arsenal fans alike as they aim to end the campaign with silverware. The Gunners drew last time out to lowly Brighton, with their current run being less than spectacular and they will need to be alert to navigate past Valencia at the Mestalla.
