Tbh, I think the club's midfield purchases over the last 18 months or so have all been with a view to replacing Pogba, and considering the writing was on the wall as far back as 2019, I don't think you can blame them.
Bruno was brought in as the 10 at a time when it was considered that Pogba was off that summer. Six months later, the alternative to/replacement for Pogba as the 8 came in the form of VdB, as there were rumours of Juve being in for him in summer 2020 (in fact, The Athletic even said that Juve went as far as having a bid rejected for him). The only thing to get now, is the DM, which was a need regardless, as Matic is in the final two years of his contract and has lost his legs in any case.
Circling back to VdB, and while he is a different player and profile to Pogba, granted, I do think we'll see a much better VdB this season than last. The reason why I think that is because he'll be playing with a player who has a complimentary profile in Sancho and we are also looking to play in a more suitable system for him (433) more often as well, moving forwards.
Tbh, I'm not too fussed re Pogba staying or going. I retained faith in him on the whole (save for a few points where I did waiver) but I think we've gone past the point of him being the embodiment of this team, and we are now (in a sporting sense at least) not beholden to him in the way that we were during the summer of 2019. Whatever happens, I wish him all the best and truly, I don't have any hard feelings towards him. He could have done better for himself, but so too could the club.
The only shame is that after 3 years of Jose forcing him in to an ill-fitting position and two years of dithering by the club in getting the players Ole wanted (and which Pogba needed to have the platform where he could truly express himself) the moment the club seems to finally be matching the ambition of Ole and Pogba, the latter looks like he may very well be leaving finally.
