Only Messi Old here? Ronaldo and Ramos? None of these three will be able to serve for very long. Ramos is currently in critical condition. He has yet to perform in a match this season. If Newcastle wants to make a long-term plan, they must focus on their young players. Try to get young talented players in the team, at the same time appoint an experienced coach.
It's just for fun. I don't think it will be that easy to bring in other players. Even though the funds are not limited they will face problems regarding the spending of the player's spending money. Because fifa will arrange FFP to get rid of the monopoly of rich clubs by buying lots of great players. I don't think they will be able to buy players in the near future. Maybe they need to keep an eye on the potential players they want.
