Midfielder Aaron Ramsey is set to travel to France after training on Tuesday ahead of Wednesday’s Group F encounter at the Stade VÃ©lodrome.
Gunners boss ArsÃ¨ne Wenger, whose side are two points behind Marseille in second place in Group F, has warned his side that they will face a stern test against the Ligue 1 side.
“They have potential,” said Wenger. “They have a good midfield and have players like Lucho Gonzalez, Benoit Cheyrou, Stephane Mbia.
“It was a complete surprise to me that they beat Dortmund like that. I was impressed by them.
“Marseille can be dangerous because they are good on the counter-attack. I think at home they will try to play like that against us.”
Meanwhile, defender Thomas Vermaelen has committed his future to Arsenal by signing a “long-term” contract extension at The Emirates.
The Belgian centre-half, who is currently sidelined after undergoing surgery on his left ankle last month, says he is thrilled to have put pen to paper on a new deal.
“I always had the intention to stay here,” he said. “I feel there is a big belief in me from the club, from the boss and from the fans and that is one of the reasons why I stayed.
“Arsenal is a fantastic club. We have great supporters, weâ€™re doing well financially and we are playing with some quality young players now and they will develop, which is very good for the future.â€
Wenger added: “Our plan is always to sign top quality players and with Thomas extending his contract, we have done just that.
“Thomas is a special player, who has always made a huge contribution on the pitch and we are looking forward to him being a part of our future.”
