It's exactly the same situation.
Every club, before making a move to the other club, gets in touch with a player's agent to see if the guy is interested.
Bayern made a "sondaggio" to Vidal, he was interested.
Juve made a "sondaggio" to Matuidi, he was interested.
Marotta asked Vidal if he indeed wanted to leave to Bayern and if he would accept their contract offer, he said yes.
PSG did or do the same with Matuidi.
Then teams will proceed to negotiate the fee. If it's not good enough, you just dont do it. Point blank. Thats for both clubs.
If every player who gets a decent offer grabs the club by the balls, we are fucked. It's not how it works. Contracts exist not only for the interest of the player. It's a mutual parties bond.
I just think this is a poor decision, and as I said before, it's not only about Matuidi quality, but about his characteristics.
We've got rid of important assets (i.e., young players with resale value) in a very short space of time (Vidal, Coman, Pogba, Morata, even Pereyra and Zaza) and now we are clearly unbalanced in terms of age.
Even Lemina has already said that his priority is "to play", and that's not happening a lot now, probably. We need WC experienced players and to develop youth at the same time, and that is a big questionmark now.
Marotta will need to sell one or two of these too many 28-32 yrs players we have the next years and replace with WC youngsters, if we want to keep financials in a healthy state.
