-He is not accepted as equal with many prestigious managers and he is presented with insulting options.
-He lacks the negotiating skills and experience to make a deal of this level happen. He has been gaining international prestige, but still not up there, in this level.
-Our board apparently does not trust him enough to authorize him a deal of big salary demands, or they just dont want them to happen, as this financial strategy kep us afloat, when the other Serie A giants went down.
-Marotta himself prefers to make more small deals of mediocre level players,or older players who are about to retire, in a couple of years, instead of good one with long perspectives, that wont give an opportunity to justify more new transfers in the coming transfer windows. For example, he got Pogba, just to sell him in a couple of years and replace him with new transfers, got Pirlo who was also bound to quit professional football in 2 years, got Vidal with the intention to sell him in 2 years too, got Khedira after losing half of his match days 2 consecutive years etc and is likely to require a replacement or complement soon.
-Fabregas is still fairly young and healthy and will forbid the justification of Mediocre mediocre CM group of transfers and is unlikely to be sold too, as he prefers to respect his contract and leave as free agent, his current manager Dein has only EPL players and made a good deal with Man City for Clichy, profitable for all parties, which is most likely to happen again.
Managers are taking an official cut from a deal and sometimes an unofficial too, some managers prefer the big deals, others prefer the smaller ones, both player managers and team managers,
so sometimes the decisions they made, also take that into consideration.
Darren Dein is well into the big time EPL player contracts, as he has the contracts of Fabregas, Clichy and RPV, players of such prestige raise a lot of eyebrows and the biggest and wealthiest FCs are willing to play a lot of official and unofficial cash for them. Approaching his agent and give him black money and/or other favors is sad reality
and this higher circle, most of the lower life transfer managers are excluded, even if they have a decent offer on their hands.
Marotta has many times proved that he is unable to make such deals happen, even when Juventus, as a club was a decent destination for the player we aimed for...
For Daren Dein its a risk to expect some black money or favors from Marotta, whilst he knows what to expect from Man City or PSG...
