FIFA announced on Wednesday that they are to allow the summer transfer window to be moved and has recommended player contracts be extended until the season ends.
Arteta told Sky Sports: "I'm planning two or three different scenarios that we can face.
"Depending on one of those three, we will be able to do more, less or nothing.
"We have to react daily. We don't know what the financial situation is going to be, we don't know the rules, the timing, the window. There are so many things we cannot control at the moment."
