The Gunners made the worst possible start to the 2013/14 campaign on Saturday, as they slipped to a 3-1 defeat at home to Aston Villa and had Laurent Koscielny sent off.
The Emirates Stadium support made their feelings known throughout a forgettable contest for the hosts, with Wenger's failure to bolster his ranks this summer coming in for widespread criticism.
The Frenchman claims to understand the frustration in the stands and insists he is doing all he can to find fresh faces.
He is, however, looking for those already on his books to raise their standards - making the recruitment of big-money signings less of a necessity.
Pressed on why he has failed to spend during the current window, despite money having been made available, Wenger said: "Why isn't it being spent. I can return your question. Why isn't it being won by the players on the pitch?
"We do not spend the money because we do not find the players. I am not the only one for that.
"We have a team that works on that and if they are not ready then that is good enough for us.
"I am disappointed when our fans are not happy, but we haven't lost a game because of our performance.
"We are in the market to buy players. Everybody knows, but until we do we have to win games."
