Dont believe everything Real put out. They're nowhere near in as bad a shape as Barcelona are.The fact they’re being reported as skint and are in a heap of debt - compared to clubs who have an almost limitless pot of money to tap into and can skirt the rules because of their state backed ownership - are a bit different.
Buying Mbappe is Perez giving PSG a massive slap down. PSG were giving it large if you like after getting Messi. This is Perez pipping them down. They could've waited a year and got him for free.
