The problem United will have when it comes to fixing this mess is that selling clubs will immediately slap a tax on any players United want.
Unless they get some really shrewd operators who can find bargain release clauses, there's no way they'll be able to get in the quantity and quality of players needed within FFP.
They need to forget about the big name (and wage) signings. Similar to what Klopp did with the likes of Grujic, Klavan, Matip, Wijnaldum, Mane, Solanke etc - go after proven prem experience that won't break the bank or come in with huge expectations or wages.
Mbuemo, Ait-Nouri and even someone like Will Hughes or Lemina would add the depth and know-how they need. There's a few off contract guys that would be interesting too - such as Aina, Decoure, Reinildo, Calabria, Anguissa, Tyrick Mitchell. Lamptey. No doubt they won't bother with any of those names though and instead throw big cash at Cunha, Gyokeres, Kimmich, Davies etc.
