It could be Wenger is feeling the pressure and the club is putting out rumours about several decent players, that might keep the pressure off of him until he starts winning again.
Then when the window is closed he will say, it’s all ok, we only need one player to replace Sanchez.
Wenger has never bought more than one top quality player in the same window and I don’t think he is going to start in this window.
It will be the same tired excuses like “we tried” “they didn’t meet with our valuation” "we couldn’t get the deal done."
We might buy one player, but I doubt it will be a swap deal with Man U, and only if Sanchez leaves, which I’m not convinced he will.
