Wenger has generated in the region of £40m from the transfers but has made only one summer signing so far, Thomas Vermaelen from Ajax for £10m.
The Frenchman insisted, however, he is not in a rush to spend the cash.
"I feel we are strong enough but if we can add then we will do it," Wenger told the club's official website earlier this week.
"In England, people think all problems can be sorted out by buying players."
Arsenal have been linked with a host of players this summer but Wenger says the club are not "close to signing anyone at the moment".
Defenders Brede Hangeland of Fulham and Newcastle's Sebastien Bassong as well as strikers Klaas-Jan Huntelaar of Real Madrid and Bordeaux's Marouane Chamakh have been linked with moves to the Emirates Stadium.

"We have money available so for us it is now important to spend it in the right way when we do it or if we do it," added Wenger after Arsenal's 1-0 friendly win over German side Hannover on Wednesday.
"The biggest target is to work hard in training, improve what we can improve and have confidence in the players that we have."
The lack of summer signings, the departures of Toure and Adebayor and the serious injury to Samir Nasri has put the spotlight on the club's transfer policy.
The Gunners lost out in their bid to sign Felipe Melo from Fiorentina, with the Brazil midfielder opting to sign for Juventus instead.
Since moving to the Emirates Stadium in 2006, the Gunners boss has focused on nurturing young players rather than capturing experienced stars.
The likes of Mathieu Flamini, Gilberto Silva and Alexander Hleb have all left the club, while Wenger has developed the talent of youngsters such as Theo Walcott, Aaron Ramsey and Jack Wilshere.
But Arsenal have not won any silverware for four years and finished a distant fourth in the Premier League last season, leading to a lively shareholders' meeting back in May during which Wenger criticised the negativity of the Emirates crowd.
