The Arsenal boss, asked about continued speculation linking his side with the Napoli striker, said: “Cavani is a player that I like. Will he cost a lot of money? That's for sure. Nobody would deny that.
“[But] our banker lives just next to me at the moment and he is ready if we find the right player."
Cavani has scored 16 Serie A goals already this season.
The Arsenal boss also confirmed his interest in Zaha, while at the same time reiterating that he has not made a bid.
"We are looking at him, but at the moment we have not made any bid for him,” he said on Zaha. “I don't know if Manchester United are in for him.
“Anyway, if you call any club for any player, they will tell you Manchester United, Milan, Real Madrid are as well in for him, but it is always difficult to know if it is true or not."
Wenger said he was content to bide his time in order to secure his targets at the right price.
"The prices always go up at the start of the transfer market and go down in the last week,” he said.
“Sometimes as well they go up in the last week, but it depends. Most of the time they go down in the last week and you know as well that 90 per cent of transfer activity happens in the last week, if not in the last 48 hours."
