Arsene Wenger admits that Arsenal could struggle in this year's Champions League, after being drawn in the perennial 'group of death'.
The French boss affirmed that it was the toughest group to be drawn in the tournament and that subsequently his side will have a fight on their hands if they wish to progress.
The Gunners will kick-off their European adventure against Marseille tonight, and will also face trips to classy Serie A outfit Napoli and last season's finalists Borussia Dortmund in a bid for qualification.
Under Wenger, Arsenal have not fallen at the first hurdle since the 1999/2000 season, but the Prof admits this campaign will be harder than years previous in terms of Arsenal's chances of making the knockout rounds.
"If you look at the group, I would say yes it is the hardest group because all the four teams have a chance to qualify. That means the every game is basically a very important one," Wenger said.
"On average you need ten points to qualify so that gives you the task – ten points in a group is difficult as that could be a reasonable number to get through."
The Arsenal boss also highlighted the importance of tonight's game against Marseille, which his side will realistically have to get three points from to ensure they are in a strong position.
"You need points away from home and as you know, like in every competition, the start is very important for the confidence of the team and to put you in a good position so tomorrow we start," Wenger added.
The north-Londoners, who are currently sitting second in the Premier League, have been boosted by the confirmation that landmark signing Mesut Ozil and top goalscorer Olivier Giroud are fit to play, despite initial fears they would have to sit out.
