Tuesday will be a 'crucial one' "arsenal vs Dortmund,Barcelona vs Ac milan.

We have started well, we have a very strong team and we have more experience as well,
The Gunners have taken maximum points from their first two games but now face a double-header against last year's finalists.
 
We have two very difficult games coming up against Dortmund," said Arteta. "After that we will know exactly where we are in the group. They are a very good side and they are doing well in their own league.
"Winning the first two games makes a difference and now we have a massive game at home. If we win that one we are almost there. I think this is going to be a crucial one."


Arsène Wenger's side have made an outstanding start to the season both domestically and in Europe but Arteta insists it's still too early to tell if Arsenal can go all the way in club football's elite competition.
