A lot depends on how much of a say Ange had over recruitment.
As always, the fickle fans in here flip flop too much. One minute he's the reason they signed. He's on the phone convincing them to come to the club. When the player is shit, it was all Levy, it's not his (ange's) fault, he hasn't been backed.
The truth is unknown. We fans have absolutely NFI how much of a say managers have/had over each individual signing. You can't just pick and chose at will which ones were manager signings and which were club signings though.
