I think the issue for some of us is the meaning of the word 'significant' in this argument. For me, I do think there will be significant overhaul of the first team squad in the summer. But I do NOT believe that means a massive outlay of cash. Significant to me meaning a lot of players leaving, a few coming in on reasonable fees, and integration of a few academy players.
Eriksen, Lindelof, Evans, Casemiro, Antony, Sancho, Rashford, Malacia, I think will all be gone for sure. (I'd love to move on from Mount and Shaw but what are the odds of that at this point? Slim I would imagine) Also, it's maybe more hope than expectation on Casemiro and Rashy given wages and form/age/current ability.
How many of those leaving NEED to be replaced? Without replacing them at all the first team squad would be at 23 players if we include Heaven, Gore, Amass, Wheatley, and Collyer. Can we add to that group Obi? Kone? A Fletcher? Scanlon?
We need an elite striker and then reinforcements in the middle of the park. If we can get a few under the radar types on reasonable deals then I could see a significantly altered first team squad for a net spend of 80 million.
