The Welsh club have won back-to-back league games against the Gunners - including a 2-0 win at the Emirates last month that left serious question marks over Wenger's future.
He said: "Swansea are a team who have already shown they are at a good technical level.
"They adapted very quickly to the Premier League - and they can buy well, as they've shown again this season with players like Michu.
"Swansea were very good when they came here. We have to give them a different response."
