Offloading them is acknowledgement of looking towards the future rather than getting stuck in the past. Because the past will never return. Messi isn't going to be pre-2017 Messi magically if at all. Barca won't be the 2009, 2011, and 2015 teams at all. I hope the new club president points that out.
No doubt. And we need to quickly get the manager that will be in charge of rebuilding. Plus draw the plan regarding the style we will try to play. Because a good part of rebuilding is not only transfers and player names. A good part of rebuilding a successful team is trying to play every week the same. Repetition and routine is how you create a top team. Going at it each week with the same purpose will make you better if you have the right pieces on the board (president, technical director, manager, players).
Get the manager and the supporting staff right. It's key. Otherwise you're going to enter a resetting pattern, every 2 years new players and new managers, and the rebuilding never gets going really. Exactly the problem of United. After 7 years of rebuilding, only recently they started to get somewhere. Because they were undecided where to go and what to do.
