Manchester United don't have funds to waste again. Last season, during the summer transfer window, Ten Hag was supported with a huge amount of money in order for him to sign quality players to boost up the club performance, but he couldn't get any. Rather, he bought average players very expensive. Therefore, Manchester United management have decided that, if they don't sell those players in the overhaul list, they wouldn't buy additional players.
manchester united did spend a lot of money on transfers under ten hag, but they didn't get the performance boost they wanted and instead wasted so much money on those players, and it ended up hurting their finances now. and now in amorim's time, manchester united are more cautious about spending money on player transfers and plan to sell players to be able to cover transfer fees this season. they are prioritising sales, exits, and freeing up wages before making decisions which is quite good for the team and makes more sense than spending crazy money again, but they don't get the players they expect.
