The lads will be previewing all of tonight's Champions League games on Off The Ball so tune in from 7pm.

Arsenal could qualify for the Champions League knockout stages tonight if everything goes their way.

If the Gunners beat Marseille and Borussia Dortmund fail to beat Napoli, then Arsene Wenger's men will advance from a group which has been termed the Group of Death.

Arsenal are still without Lukas Podolski, Alex Oxlade-Chamberlain, Yaya Sanogo and Abou Diaby.

But they welcome back Mathieu Flamini from suspension and Theo Walcott is available for his first Champions League game since May.

The Gunners beat Marseille 2 - 1 at the Stade Velodrome back in September, a game in which Walcott and Aaron Ramsey scored.

Walcott, who was Arsenal's top scorer last season, will add another dimension to an already formidable attack, adding extra pace and width on the flank. That should give Mesut Ozil and Santi Cazorla even more variety of movement to pick from in the final third.

Meanwhile, the French side have lost all of their group games so far and are currently fourth in Ligue 1 - five points off the final Champions League spot.

The diminutive Mathieu Valbuena

Marseille won 3 - 1 away at Corsican minnows AC Ajaccio at the weekend to make it two wins in their last two league games. Prior to that they had failed to win their four previous games but victory over Ajaccio came at a cost.

They have lost Ghana international and winger Andre Ayew for two months following knee surgery.

But the club from the Mediterranean still have a number of key players such as France attacking midfielder Mathieu Valbuena (five assists in Ligue 1 this season), striker Pierre Andre Gignac who has scored six league goals as well as tricky winger Dimitri Payet and Arsenal's summer target Florian Thauvin who was featured on my Scouting Report before he signed for Marseille.

Other players to look out for are 21-year-old defensive midfielder Giannelli Imbula who has been linked with a big-money move to Chelsea, goalkeeper and France international Steve Mandanda, Ayew's younger brother Jordan who also plays on the wing, Camerron defender Nicolas N'Koulou and midfielder Alaixys Romao.

Indeed, Marseille have a much younger squad with many players in the 21 - 23 age bracket. It is a deliberate ploy from the club's hierarchy who are going for a policy which sees them bring in talented youth with high resell value.
