Having let a two-goal lead slip last weekend, Arsenal will look to translate their fine European form into domestic success when they face newly-promoted Aston Villa in the Premier League on Sunday.
Unai Emery's side let Watford snatch a point off them previously, and are sure to be wary of the Villans managing a similar trick.
Dean Smith saw his team play out a goalless encounter with West Ham previously, but he will know that a shock win against the Gunners will go a long way towards strengthening their claim to avoid a relegation dogfight.
