We're of similar thoughts you and I.Depends
If he identified and managed to bring in Gray, Solanke and Bergvall and also told Levy he needed more incomings and baldy refused to comply then it's not on him
If he identified Gray, Bergvall and Solanke and himself decided that was enough and has sat on his arse since then then he's fucked up bad
Nobody knows how we operate though. We hear Levy has stepped back, then we hear Levy has got personally involved. Truth is nobody really knows how much Levy sticks his oar in but given we continue to be cheap we can be sure he sets the financial rules of any deals.
I'm willing to bet Lange is also working with one hand tied behind his back though. He's probably on orders to be in Scotland scouting managers instead of players.
Given the steady stream of players in at Villa under Lange, this definitely feels like he is being hamstrung from up above.
