A victory in Moscow will virtually put Arsenal through to the Knockout Stage of the Champions League, according to Arsène Wenger. But the manager knows his side will be tested fully by the conditions in the Russian capital.
If Arsenal win on Tuesday they will be five points clear at the top of Group G with three games to go - two of them at Emirates Stadium. However Wenger has taken his side to Moscow twice before - Spartak in November 2000 and Lokomotiv in September 2003. He is yet to register a win.
"They are a good side," said Wenger. "The chairman of Porto said to me after our match that they had been impressed by CSKA Moscow.
"They have some good Brazilians there and also seven players from the Russian national team, which is a solid combination.
"While I feel we can beat them, you always have ingredients in Moscow during October that you cannot master. I have heard that the quality of their pitch has been destroyed by a tournament, and it is already cold there now.
"A victory would nearly qualify us, so of course we will really go for it. We want to qualify as soon as possible, because it is always a relief. You can go into the winter and focus on what is coming next."
