Cottagers manager Martin Jol has landed Darren Bent and Scott Parker.
Wenger told arsenal.com: “[Jol] has got one goalscorer, one guy who can give the final ball and one guy in the middle of the park with a lot of experience. [They are] good signings.
“Parker is maybe not the youngest anymore but what you lose a bit with maybe physical quality, you can gain in positioning on the field and guiding other players.
“He has always been very motivated and he still has that hunger. Even for Tottenham last year, he was an important player and for me he's a good signing.”
