Marotta has said this many times, the player's will is of import with regards to selling. Vidal is a starter, if this deal does go through then it is the player's decision and it is the club's responsibility to get as much money as possible.
dude it's not just the fact we're selling him, we're giving a terrible message for the rest of Europe. The fact another big club buys a player from another is never a good message.
Not to mention the reported 40 million euros, this is penuts to how much players are sold today
Di marzio kept going on and on about cavani to juve even after Marotta denied it then he eventually stopped and people just kind of forgot about it and moved on
