Wenger: Arsenal are in toughest Champions League group
"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," he said.
"That means the every game is basically a very important one.
"On average you need 10 points to qualify so that gives you the task - 10 points in a group is difficult as that could be a reasonable number to get through.
"[Away games] will play a big part because it is difficult to predict that you will absolutely win your three home games.
"But anyway, 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.
"Is it home or away? It is the same, basically, we come here and we will try to win the game."
