Are you sure that star players will go to Newcastle now. I think not. Star players, in addition to money, need trophies and the opportunity to declare themselves. They think about money at the end of their careers. There are a lot of things to do now before you start buying players. You need a coach, a development program for the future.
Kylian Mbappe right now is in no mood of joining Newcastle, as his mother confirms that his talks for staying at PSG are underway (

Its too early to say that whether such big names will join Newcastle after recent take over by Gulf businessman, the club need an overhauling process where they need good coaches and good performances that can attract big players to come and join the club.
I don't think any star player is interested in joining the Newcastle team now. Star players will definitely want more wages, at the same time, they will definitely want to play with the same good squad and will want to win the title. Newcastle will probably provide many wages. But they can't afford to fight for the Premier League title. And I don’t think it will happen next season either. They have to slowly sort out the team.
