Wenger told reporters: "What is important is we look at how we finish the season, how well we play and make the decisions who to buy and who to sell at the end of the season.
"This will be influenced by the way we play in our last nine games. But what is important is to analyse where we can improve at the end of the season."
The Arsenal manager has been disappointed his team did not fight for the title this season, and acknowledged “blips” in the domestic cup competitions – but was overall pleased with the attitude shown by his side this term.
The 63-year old continued: "What is for sure is that we didn't fight for the championship. What is for sure is that we have had some blips that were not expected -Blackburn and Bradford.
"But, overall, I must say the attitude of the team has been great and when everyone is here we have a strong team."
