Udinese VS Arsenal

Play Off Second Leg - 20.45 CET (Local Time) 19.45 BST ( UK Time)

Arsenal travels to Udinese this evening for the second leg of the Champions League play off, with the narrowest of leads. Arsenal take a one goal lead to Italy after Theo Walcott's fourth minute strike gave the Gunners victory at the Emirates on 16 August.

The two clubs have never met in the Champions League before last week's meeting and it is the first time the sides have met in Europe. Arsenal have a decent record against Italian sides in the Champions League, winning 12 matches, drawing eight and losing just six.

Arsenal has only won one of their last eight European away games away from the Emirates with their last victory coming away to FK Partisan, winning 3-1 on that occasion.

Arsenal have failed to score in either of their Premier League matches to date but will know that an away goal would put them in a strong position to progress and Robin Van Persie is back from his European ban, while Gervinho, Alex Song and Emmanuel Frimpong are available despite domestic suspensions.

Nasri has been left out of the squad after a deal was agreed with Manchester City, while Jack Wilshere has still not recovered from an ankle problem.

Also missing will be Laurent Koscielny (back), Nicklas Bendtner, Abou Diaby (both ankle), Kieran Gibbs (hamstring) and Sebastien Squillaci, while summer signing Carl Jenkinson could start at left-back.

Wenger will at least be able to coordinate proceedings from the dugout despite breaking the terms of his touchline ban in the first leg by communicating with the bench.
