Wenger will now turn his attention to the transfer market after guiding his side to a 3-0 first-leg win over Fenerbahce in Turkey on Wednesday night.
The Gunners boss, who missed out on the signing of Gonzalo Higuain earlier this summer, feels the transfer market will now kick-start, but ruled out making an improved bid for Liverpool striker Luis Suarez.
"(There is) absolutely no chance of that," said Wenger when asked about Suarez.
Wenger, though, stressed he was looking to strengthen, especially in midfield, with Mikel Arteta and Abou Diaby both also sidelined.
Newcastle United midfielder Yohan Cabaye and Real Madrid striker Karim Benzema are reported targets for the Gunners.
"We tried to bring one in, but we are working on that. You have to understand there is still a long way to go," added Wenger.
"The transfer market starts for me now and a lot of activity will happen between now and September 2.
"From August 21 until September 2 you have 12 days, so a lot will happen. It starts now.
"It is like a poker game. People hold their cards as long as possible and see what is happening out there. In the end, they go for decisions."
