I agree he's unlikely to come, but he can't exactly be thrilled by being 23 points adrift of Bayern in March. And he can't be blamed much for that given what's happened to Dortmund with transfers in the past couple of seasons. They're hopelessly outgunned.
I reckon a manager similar to Klopp is what we need - an established manager at about the same level as Wenger who will actually feel under pressure to succeed.
I'd also like to see us hire a charismatic manager who comes with a real tactical technocrat as assistant. We are going to need a shakeup behind the scenes when Wenger does move on.
