Arsenal face a stern test of their title credentials when they take on Aston Villa on Saturday evening.
The Gunners sit top of the Premier League table after grabbing a late winner against Luton in midweek and travel to Villa Park to face their former boss Unai Emery.
Under the Spaniard's management Villa have registered 14 consecutive home victories including a dominant 1-0 win over Manchester City on Wednesday.
Arsenal will need to be at their best to topple Emery's outfit and they will have to do so without their manager Mikel Arteta.
