How do you think transfers happen mate?
I'd say it's pretty safe that he does no budgetary or negotiating, he simply selects targets and coaches the first team.
The negotiating and deal brokering is done sepreatly by the club.
Your post might be true back in the 80s.
I'm not suggesting for one moment that he actually negotiates, but the players that have been signed are down to him and him alone.
He's messed up royally mate and you know it.
