That seems to be the trajectory for a number of Wenger's summer deals. The dialogue for the devil and angel on his shoulder is something like this.
Devil: "Hmm, we have an opportunity to sell Player X for a decent fee. We should really do that."
Angel: "But Player X is a vital cog in the Arsenal machine!"
Devil: "Player X has been kind of a dick lately."
Angel: "You've known Player X since he was fifteen!"
Devil: "There's still time to replace him … and it is a very decent fee!"
Angel: "B—b—…"
Devil knocks Angel unconscious.

…
One day before transfer deadline. Angel awakens, groggy.
Angel: "Have we found a quality replacement for Player X?"
Devil: "Weeeeeell … not exactly …"
Angel: "There's only a day left! Who's available?!"
Devil: "Weeeeell … would you take Declining Ex-Manc Scum?"
Angel: "No!"
Devil: "Weeeeell … I guess there's always Player Y, right?"
Angel: "But he's a crock!"
Devil: "That's all in the past. He hasn't had a fatigue injury in at least six weeks."
Angel: "He's not that good either."
Devil: "He's a full international."
Angel: "They're ALL full internationals …"
Devil: "What about that day we played Hated Rivals M?"
Angel: thoughtfully "It's true. He was pretty good that day …"
Devil: "Good? He was fucking glorious!"
Angel: "True. But then he was out for three months—again. Look, I'm still not sure about—"
Devil: "Come on, it'll be fine. This transfer window's as good as over anyway. First round down the pub's on me ok?"
Angel: "Oh, ok."
