You pay for
signing if you had, say, 27 millions before the signing and don't have them after the deal. You pay for
selling if you have -27 on your sheets after the deal. If you have a 70-million profit after the sale, you not only paid nothing (i.e. get something for free), but gained a hefty sum o money. And those 27 millions were needed to paid
only when you get your 70. You didn't pay anything in advance (unlike money already spent/set to be spent on salaries for Rabiot and Ramsey).
That wasn't my point, I explained the logic above.
Yes, and I already commented this fact.
You proposed "at least 50 millions", I said "yes". Isn't that the answer

?
No, I wouldn't. PSG don't give a f**k about money, they were ready to pay the price that had to paid to teach this young man some good manners.
Arsenal management being a joke is something they are well-known for. That's why I wrote that, yes, they were stupid in their actions when they already had that guy. Especially considering the fact that they are financially stronger than Juventus and it would be much easier for them to keep him than for Juventus to sign him. But they are the Arsenal management, so...
That's true, and that's what I was talking about several posts ago. What I'm talking about now is that let's not call brilliant free signings what don't really deserve such a praise considering the facts
we have now.
