Agree with you on our youth set up - We paid a fair bit for Amad, and he's a decent player, why not see what he
Kodi can do?
I would keep Case and Varane at least one more season though, while they're both out of form right now they both played well for the team and are good personalities for the team - add in a young CB and CDM next season, and get the 2 experienced serial winners to mentor Kobbie and the aforementioned summer buys. McTom is not a terrible squad option, surely not worse than Phillips at City I feel, but shouldn't be a regular starter.
New younger CDM, Kobbie, Mount (I do expect him to return to his best), Bruno as starters with back up from Case (could of course start if he's fit enough), McTom, Gore and another youth player next year are good options going forward. ,
New younger CB, Varane/Maguire, Licha/Victor I think is enough for next season at least.
Forwards - Rashford and Antony are out of form but I think they can be given a bit more time to come good, but they both need to step up. We've also got Garnacho as a mainstay (LW) and Pellistri (RW) as a back up, I would also see what Amad can do this season. Rasmus only currently has martial as cover, so I'd look at recalling Greenwood (Controversial maybe, but I mean if we don't give him a second chance, another top club will) and getting an experienced striker in January (loan deal, reasonable wages) to ease the pressure in that position.
Get rid - Sancho (Unless he wants to be a United player and is willing to work with his manager and produces better performances on the pitch) + Martial (Nothing against the guy, but I don't think he's capable of being that experienced striker that eases the pressure on Hojlund/Mason when he's injured so often). Eriksen and Sofyan also need to go - We should look at loan replacements for both.
Ins: New young CDM (Mould of Camavinga), New young CB (Todibo maybe), Experienced CF (Loan), a technical midfielder for the number 8 role (Loan), experienced CDM (Loan)
Outs: Martial (End of contract), Sancho (Sold to the highest bidder), Eriksen, Sofyan, probably Donny as well.
If we do have the money for it, maybe we go for an experienced Striker who's 27-28 via a transfer (Rather than a loan) that can give 2 years to United, that we can sell on for a decent fee once Hojlund/Mason are ready to lead. This United are not necessarily a bad team imo and I feel like we tend to judge our players quite harshly compared to others (Mainly because we've spent large fees) - A younger team takes the pressure of playing for United/ pressure of the price tag down a notch, but also solves our 'expensive-toxic-mercenary-one-trick quick fix buy' problem that has plagued us for a number of years, but for this to succeed the manager (Whether it's ETH or anyone else) needs to be given some trust and time.
