Les Ferdinand
Sure, I do understand the realities and intricacies of making these moves. I will caveat though that in the case of Fernandes, he didn't move to United instead of us. He moved to United because we couldn't close the deal with Sporting, with whom we had a free run at. His move to United came 6 months later.Outside of the very biggest clubs in the world, most of the time you don't get your top targets - the players you mention went to Liverpool and Man Utd who are two such clubs.
This is the problem a club the next rung down in the chain is always going to face - Any coach outside of the true big boys in Europe are going to have to accept you aren't going to get your most most desired. So Poch would have to work with alternatives outside of his first choices, just like 99% of football managers do....
I only mentioned these names because Ndombele and Lo Celso were brought up when neither were actually the very first choices wanted. Maybe if we had actually been able to get first choices we might have kept the squad and starting 11 quality high because one rule we've never understood is if your squad even stands still, it's actually going backwards and that's what happened to us on 2016-2019.
