Why is that so important? It's undoubtedly very important to Juve to break even and not register any losses. It's obvious how important it is from the way we behave with some players, where we'd rather let their contract expire and lose them for nothing (but not register losses) than sell them for less than their "yearly worth" and register as little as a 0.5m eur minus in the books.
I really don't understand finances and financing
