Is there a manager that gets exactly what he wants? Pep wanted Kane and even he didn't get him.That whole he's been backed/not convo is kinda flawed to be honest.
To me, a manager has been backed when he got exactly the players he wanted, his top options. And all of them, not being left 1, 2 or 3 players short come the end of the window.
For instance, you ask for say Nico Williams but your board says no, transfer fee + wages too high...you can have 50 mil + 80k pw Brennan Johnson instead. Has he been backed cause we spent 50 big ones on a player? Or was he not backed cause he got the B side? By the way, I'm not saying Ange wanted Nico over Brennan (which is another debate).
Either you back your HC or you don't, there's no in between IMHO. Issue is, that's Dan Dan's MO right there...doing 30-40% of what's required, always. See Jose get Rodon instead of Skriniar or many another example out there since '01.
I think nowadays football clubs don't operate like that. They have people within the club who also make decisions on who comes in.
