Well, we don't know what is going on do we. If rumours are to be believed, he punted more for Jones than Utd. That's hardly dithering.
I'm more inclined to wait and see what happens, and call him out if we reach deadline day without the required investment needed. It's clear he won't be ousted as manager, so we're stuck with a two month wait, like it or not.
It's better to burn out, than to fade away.
You think he would like to have his main buys in for July 1st or whenever pre-season starts.
He does normally get his most expensive deals done in advance in June/early July.
It's the cannon fodder that follows as we get closer to August, when he decides to plug a gap in the squad with someone cheap and cheerful.
