Are Arsenal done for the window?

Take this with a huge grain of salt, because most journalists are saying that Arsenal are doing for the window, but Wayne Veysey, who has been more reliable this summer, and GeoffArsenal are both saying they think Arsenal are still after a striker:

I would be amazed if we haven't got a contingency plan re a striker in case Ba deal dropped.

Arsenal striker twist: Told AFC are working on a new deal for a forward. Unlikely but not impossible.

These aren't the most reliable of sources, but there is just an hour left, and sometimes Geoff has info before others. Also, it makes sense: If Arsenal didn't have a contingency plan beyond Ba besides Nicklas Bendtner, that'd be putting a lot of hope into a) Olivier Giroud not getting tired/injured and b) Nicklas Bendtner being a competent striker; both of these options are risky. Arsene Wenger has said he's prepared to overspend, so I wouldn't be surprised to see Arsenal at least try for a striker.
