United will hand Amorim a £200m warchest and also support a clearout of up to nine senior players, which they believe can save £80m from their annual wage bill.
United will seek to sell their four players away on-loan: Marcus Rashford (Aston Villa), Antony (Real Betis), Jadon Sancho (Chelsea) and Tyrell Malacia (PSV).
Offers will be considered also for Casemiro, Andre Onana and Alejandro Garnacho, with Kobbie Mainoo another available.
A club insider told the Mirror: “It may be a case of swallowing big losses on what was paid for Sancho, Antony, Casemiro and Onana, but there is an acceptance that the manager must be given the players he needs to make his system work.
“Off-loading some of the biggest earners at the club will also create some wriggle room for the necessary rebuild.”
