The Gunners return to European action for the first time in just over four months, after they topped Group A to ensure they avoided the dreaded knockout round play-offs.
Since then Mikel Arteta’s side have cemented their place at the top of the Premier League, with recent dramatic comebacks over Aston Villa and Bournemouth further strengthening their title credentials with only 12 top-flight games to go.
For now though the focus is on Sporting, who finished third in their Champions League group earlier this season despite taking four points from their two matches against Tottenham.
