The Gunners are set to host Tottenham on Sunday. While star man Gareth Bale is on the verge of a mega-millions move to Real Madrid, their north-London rivals have nevertheless smashed the club transfer record three times thi summer bringing in the likes of Paulinho, Etienne Capoue, Nacer Chadli and £26million striker Roberto Soldado.
Spurs also completed three signings on Friday, with Romanian defender Vlad Chiriches joining from Steaua Bucharest and he was followed by forward Erik Lamela from Roma as well as playmaker Christian Eriksen from Ajax.
By contrast, Wenger has completed only the free transfers of midfielder Mathieu Flamini and France Under-21 striker Yaya Sanogo.
Arsenal are, though, expected to be late movers ahead of the September 2 deadline - with Karim Benzema, Mesut Ozil and Angel di Maria of Real Madrid said to be top of the wanted list.
Wenger, however, insists Arsenal - who failed in bids for Gonzalo Higuain, Luis Suarez and Yohan Cabaye earlier this summer - will never be bullied into paying what they believe are inflated fees to push through a deal.
"There is no transfer market anymore where you can say: okay, this player a right-back, a left-back or whatever. It just depends on the financial potential of the buyer. We have financial potential, I wouldn't deny that, but we will decide still to pay the right price," Wenger said.
"It is linked as well to the economical resources of the buyer.
"You could be in the position to buy a house that is worth £2m, but if you like it and you have £4m, you can buy it for £4m.
"However, that doesn't mean you can re-sell it for £4m, but just that you have the £4m and you can buy it.
"It is exactly the same with players. Monaco buy Falcao at 26 for £60m. They have 17,000 (stadium) capacity, they know it doesn't make (economical) sense, but the guy who owns the club has the money to buy him, so he decides to buy him."
Wenger maintains direct comparisons between Arsenal and Tottenham's strength cannot be drawn just on spending alone.
He continued: "I think about 'does my squad have a chance to fight for the Premier League or not?' We don't compare to Spurs especially.
"Last year, if you had looked at Chelsea's squad at the start of last year, would you have said they had a squad to fight for the Premier League last year? Yes.
"However, they finished two points ahead of us and it is in the last game that it (third place) has been decided.
"So you let people talk and you try to analyse the quality of the game you have.
"I just can say one thing, in the last six months we have lost one game."
