The lower the value the better. I just hope we sign him. Haven't watched him for Barcelona a lot but he has always impressed me playing for the Dutch national team, which one would imagine is similar to how ETH will utilize his talents.
At least on paper, we currently have what to offer FDJ. Not even taking the money into consideration, we have a manager he is familiar with and who appreciates his play. The said manager also is a bit of a planning freak, who has detailed views no what he wants to achieve and how to do it. A solid project plan seems to be way more valuable to players than being reported. Players like Kroos have said multiple times that the project is very important to them because they are singing for a big club and for a period of 4-5 years (not next year's CL as journos would have us believe). One of the most famous quotes of FDJ is when he asked the ref to give more added time because he wants to play more football. That was the ETH football he enjoyed so much and he just might be willing to relive that again.
Love your examples of players forced out of clubs and still being a success. ADM is being mentioned around a lot but it just did not work out for him with us due to multiple factors. He did play for PSG for 7 more years after leaving us, so it shows that, if things align, players can be happy playing for other club in another country. Many of the things regarding him are exact opposite of what the situation with FDJ is. New country, mentality, manager, style of play and even the club's demeanor contributed to his ultimate fall for us.
