Olivier Girioud should start for Arsenal tonight away to Marseille despite carrying a knee injury.

The French forward has scored 5 goals in eight appearances so far this season but appeared to twist his knee towards the end of the game against Sunderland on Saturday.

Defender Per Mertesacker is also available for tonight's meeting at the Stade Velodrome

Celtic are in Italy to take on AC Milan and manager Neil Lennon says he will wait until this afternoon to see if Joe Ledley is fit to play some part.

The midfielder remains a doubt with a groin injury.

But the Rossoneri have been hit with a major injury crisis. Kaka, Riccardo Montolivo, Stephan El-Shaarawy and defenders Ignazio Abate and Mattia De Sciglio are all out for the hosts.

At Stamford Bridge Chelsea host Basel and it has been confirmed Frank Lampard and Oscar will start for the Blues.

All of tonight's games kick off at 7.45pm.
