I always imagine its like this, of course I am NOT an expert, nor do I work in football, so take it or leave it.
Carlo and Brands meet up.
Carlo : "Marcel, our midfield makes me cry, I was making pasta last night and I honestly burnt pasta I was that upset"
Marcel : "But Carlo, Marco Silva spent all our money on Alex Iwobi, the cupboard it is bare"
Carlo "*Swears in Italian and checks contract."
The End.
ELEGIGGLE
No but really.
I think its a process.
They talk about areas they could improve, so they both decide they want a midfielder, Carlo tells Brands what he wants that midfielder to do, does he want him to hold, does he want him to creative, does he want him to sit, does he want him to get up and down and no, we wont get a midfielder that does it all, all players excel at certain things. So Brands goes away, talks to his scouts, has a look on Wyscout and checks his notes.
Carlo will also give Brands a few suggestions, Brands will have a look and together they make a decision.
He then goes back to Carlo and says he's got 2 or 3 players that fit the profile. Carlo then has a look on his ipad, checks all the scouting videos, checks his stats, has a look on youtube and all that jazz. Then Carlo says I prefer X player and if not Y player. Brands then goes and talks to the club, the players agent and the player and tries to get the deal done. If the deal isn't happening he moves on to player Y.
Then they repeat the process for other areas.
As for as sales Carlo will tell Brands who is and isn't part of his plans, then Brands will attempt to get that player punted ASAP.
But as I keep saying, the buck stops with Brands, he's the 1 who has the final say, he takes all the credit and all the blame.
