My guess is that Newcastle should have no worries when it comes to the club's financial condition. So that Newcastle should be able to build their squad even more in the coming season. Moreover, they must also have more mature preparation and must have more reliable troops to compete in the Champions League competition against strong clubs from other local leagues.
But it turns out I read news from a sports website about Newcastle's spending budget which turns out to be not that big. So that Newcastle probably won't be able to bring in more star players to their club. Sourch:(

They want to move with a controlled growth and perfect planning, but if they transfer a few star players to the team, I think they can have a more successful season next year. They may not be able to persuade Mbappe to come to Newcastle United, but they can persuade Neymar. I am 100% sure that Ronaldo will want to come back to Europe and the Champions League again, they can persuade Ronaldo to come to Newcastle United. If they make a deal with a few big star players in the same transfer season, we can say that they entered an uncontrolled transfer process, but if they transfer only one star player, I think their plans will continue to work flawlessly.
Newcastle united don't need much players in the squad, they just have to work the budget given to the coach by the management for new players, and buy players that is more needed to build the team. At times buying plenty players to a new developed team brings sentiment, so the coach has to sought players that will fit in immediately.
No one expect them to do better in their first appearance in champions League this season, so they have to focus more on the Premier league title, were their favourite to challenge for the title next season.
