It is a bargain. That's an amazing selection of players to bring in for hardly any transfer fee.
Wages will sky rocket but the lack of transfer fees comfortably compensates. For every 100k a week over what they think they are worth or what they were on previously that's still just 5million a year. Messi is a different kettle entirely he pays for himself but the other freebies in Donarumma, wijnaldum and ramos would have to be costing £100 million+ if they want out of contract. the wages and signing on fees would have to be astronomical to get anywhere near that. It's a great window for them before Messi.
