Arsenal duo Aaron Ramsey and Kieran Gibbs have both been rated doubtful for tomorrow's Champions League clash with French club Marseille.

Midfielder Ramsey missed Sunday's victory over Sunderland with a hamstring strain, while full-back Gibbs picked up a stomach injury in the same match.

"Gibbs has an inflammation of his stomach muscles and has a small chance of playing," manager Arsene Wenger told a press conference.

"Ramsey has a small chance of being in the squad. It would have been a gamble to play him [on Sunday]."

Defenders Thomas Vermaelen, who signed a new contract today, and Bacary Sagna have already been ruled out of the match with injuries.
