To me it's not that simple: Good relations gives a huuuge advantage in this f***** up market. PSG can trigger all of our players buyouts all at once every summer and offer double wages - how much fun is that? I hate them because of Neymar, but our own behaviour with Thiago Silva, Marquinhos and Verratti has been facepalm-worthy.
Yes, Ajax-players wants to come to Barca, and therefore we need a good relationship with them. If we can trust that they listen when we knock on the door, there is no problem with De Jong staying 1 more season without a formal agreement between the clubs - that is the benefits from a good relationship. If we get the reputation of making every target rebellious against their owner, we will lose some goodwill. Other countries don't have buyouts, so we depend on negations every time.
Ajax has taken a player that was announced to join us from our hands, got a couple of youth players from us, rejected many offers from us for FDJ and only relation we had with them was getting Jasper for a fee that made him a top 10 expensive GK in the world at that time. I am not sure what good relations we have with them that people keep talking about, it seems to go one way and judging bu their other deals it is their way in the market.
Good relations won't make a difference, Ajax isn't doing us any favor nor they will punish us, the one with highest, overpriced offer will get their player, unless that player has a smart dad and agent that tells him not to renew and get the hell out asap.
Never mind that we have almost no Dutch connections this days anyway.
And our relation with Bayern is good, our relation with most Spanish clubs is even better than RM, other than Santos who want to get us more money and BVB I don't think we have a bad relation with any club
Even PSG weren't against selling us ADM but we couldn't agree on price, Abidal is a personal friend of Nasser.
And PSG can't trigger our players buyout for fun, this summer has showed that with almost no big signings as they are careful with their FFP situation, they are playing with fire atm and overpaying for players buyouts won't work well for them
