"We are still open to strengthening our team with players coming from outside," Wenger told the club's official website. "We are very active in the transfer market and have already realised two incomings.
"We have to keep a balance as well, that you don't destabilise the team too much by bringing in too many players, but we are still active in the transfer market so let's see what kind of opportunities we can find."
Question marks remain over the futures of Alexis Sanchez and Mesut Ozil as the pair just have one year remaining on their current contracts.
Also, Olivier Giroud has been linked to West Ham United, Everton, Marseille and Borussia Dortmund.
