Garnacho doesn't really count under Rangnick, does he? He wasn't really part of that side which downed tools. Bit rum to include him.
Rashford showed for Ten Hag last season, but there's nothing to say his position is secure if he fails to show in future. He'll be sold.
Just my opinion, but there are players I'm sure he is giving the illusion they're secure, but he'll get rid if they don't match what he wants, which was kind of my point with Fred.
Rashford won't be sold. He will have to keep performing to remain in the starting XI, but he's also versatile enough he'd be kept as a squad option even if someone forced him from the first choice LW spot (Garnacho has a chance possibly), unless Rashford really pushed for a move, but in a couple years he'd likely settle for a squad role anyway.
Similar for Bruno. I think ETH obviously trusts him, as he has been played at 6, 8, 10 and on both wings when required and shows an ability to follow instructions and play for the team, even if it means he doesn't have the free role he was granted under Ole, he's definitely more than capable of fitting into ETH's system.
Also Shaw and Varane are likely to remain first choice for the foreseeable. Dalot and AWB both getting plenty of playtime and if another RB is signed next season, one would likely remain as a rotation option. Lindelof will be kept as a rotation option unless he pushes for a move, but realistically is quite well suited to ETHs system anyway. Sancho the jury's out, ETH seems to be trying to find a way to get the best out of him, he may be kept as a versatile squad option unless he agitates for a move. Martial, meh. I think ETH likes him stylistically but he's never fit.
Fred and McTominay both optimise how far behind the squad was technically, especially as they play in the position where ball retention and possession play is the most important attribute. And whilst they somewhat symbolise the Ole and Ralf eras, they are demonstrative of the squad as a whole. There are a number of quality players that a quality coach can work with.
