"If we can do one more signing we will do, it but it will need to be quality.
"We don't need money to buy someone, but it's not just to buy, it has to be the right person. That is at the moment very difficult."
Wenger - whose team were today drawn against Steve McClaren's FC Twente in their Champions League qualifier - added: "It's not a problem because we have enough young players who can step in.
"But we lost experience and if we can get a midfielder with experience who can play a tactical role we will do it."
