Wouldn't surprise me, Wenger still thinks he has 2 months left because he never see's the beginning of the season as the pojnt at which you should have made your main signings, not looking good on the striker front though, slowly but steadily we're missing out on all the decent options, we just don't get our transfers done quickly enough, that's unless he's relatively unknown like Xhaka or some kid noone wants.
We're pretty desperate for a decent striker but seem in no particular hurry. People say they expect us to sign a striker, there's two things you know about Wenger though, one is that he has a record of not doing what people expect him to do (i.e. the logical thing) and that could mean he doesn't sign one or if he does it will be some small time nobody not up to the job.
