In its current position, Newcastle does not need super transfers, because for the task of maintaining representation in the Premier League, they do not need extra-class games. It should also be borne in mind that the club has a certain spending ceiling in the current transfer window according to the requirements of financial fair play, so it is better for the club to buy several strong players than to spend all the money on a conditional one Mbappe. Newcastle is now a step away from the abyss and first you need to move away from this abyss by building a strong combat-ready team, but then it will be possible to improve this team to solve higher tasks.
Even if Newcastle want such, they will not be able to achieve it too soon. First, their current position makes them less attractive in eyes of star or super star players. Second, finance regulation in football now is very strict and they will not easily to spend fund like rich clubs did years ago. They have to buy and sell players as well as other activities to balance their finance sheet. If they over spend money, they will be under radar then punishment of EUFA like Manchester City or PSG.
newcastle just got the title of a new rich club but it is difficult for them to get or attract star players if their position is in the relegation zone, right if their focus right now is to avoid the relegation zone, and I think what newcastle needs right now is a consultant who can give advice to build the club's foundation in the future it is more useful than waste money for unneeded players. because to build a club's success doesn't start with buying star players but create the foundation of the team.
I don't call it as a title for Newcastle. It is just a name-calling which is used by socia media and the crowd. Do they care about it? I guess not and believe they even don't like it. Because a rich club name-calling only brings more difficulty for them in transfer negotiation. They will have to spend more expensive cost for same players than poor or average clubs.
Do you see English players usually have more expensive price than international players if they are at similar quality?
