Not sure why you would think this would be the case? Who is still contracted beyond 2024 who is on enormous wages? Or contracted beyond 2024 full stop? The point of parachute payments is as cover (potentially partial if you go mad like Forest/Fulham a few years back) for the wages for newly promoted teams - they can then recruit a better standard of player than they might be able to budget for otherwise in the medium term, then not get twatted 30 times a season which is in the best interests of the Premier League as a whole. They last for long enough to cover the majority, or entirety, of a player's contract, the players will generally have moved on by the time they stop. Which is exactly what we're doing?
United don't have any players on huge wages at Championship level really. Berge is believed to be the biggest earner on 35,000. The players have had 50% wage cuts when relegated and a further cut this season on what was a really low premier league wage bill (source Wilder/media) . A number of players from the premier league days have also signed new deals in the Championship (Basham, Robinson, Sharp). Baldock signed one when the relegation writing was on the wall - you'd presume his deal reflects this.
We've only made two permanent signing since relegation Anel, Davies (goalkeeper)). We do however have some youth prospects breaking into the team (Jebbo, Osula, Ndiaye, Arblaster, Gordon) and some returning loans Lowe, Coulibaly, RND, that are probably on decent contracts given their status in the game. At the end of this season we can remove Osborn, O'Connell, Sharp, Mcburnie, Fleck, Norwood, Foderingham, Robinson and Stevens from that wage bill if we so wish. We have already lost Mcgoldrick, Freeman, Verrips, Burke, Moussett, Ramsdale, Lundstram, Moore, Jagielka, Bryan and Rodwell that were on legacy Prem contracts. The loans will also go back.
The reason United didn't go big on wages is that we could reset after relegation to a post parachute world without the need for a fire sale. Having said that in an interview last year the Prince said that our plans were predicated on the sales of Ramsdale AND Berge. Whether our lack of permanent signing in the last two seasons reflect the failure to sell him, or whether we still need to sell him notwithstanding this remains to be seen. I guess we'll find out in the next week or so.
