Just because we bought Paulinho for 40m doesn't mean his actual value is that much, a player is only worth as much as someone is willing to pay for him. If Suarez keeps up his current form we'd be lucky to get 50m for him and the rest of the trash that barely get any minutes or are old could go for anywhere between 50-80m combined.
I wouldn't like for us to pay 250m for two players, but that's the price of established stars in today's market. We could also opt for youngsters that would be cheaper (Dembele is a unique case due to Neymar money), but have no guarantee of panning out. You have to pay big to get quality these days, either we adapt or become a mediocre club and hope for another Masia miracle.
My plan isn't all that ridiculous either, we can sell players to make over 100m, we have 100m from last year's window as well as likely another 100m+ from this year's window.
Yes, market prices are, what they are, but that also means there is no logical reason for us to sell cheap. We have to brake that silly FM mentality once and for all. Personaly i wouldn t be happy with 200 mil for all those players you mentioned.
Understand, that putting 250 m in two players, while selling 8 members of the team is also a huge risk. This sort of risk makes sence if a team is performing badly, which we aren t. I know our standards are high, but the summer window showed, that Barca fans are highly prone to needless panic.
