If Newcastle manage to finish the league among the top 4 teams this year, they may be able to attract the attention of high-profile players next year. For example, if they had played in the Champions League this year, they might have caught the attention of Cristiano Ronaldo. I think Mbappe will not be a difficult transfer for them. Mbappe's interest in money is also a known fact. If Newcastle make a good offer for him and they manage to qualify for the Champions League this year, they can sign Mbappe in my opinion. Also, it might be easier for Mbappe to change his mind if they sign up for a few more star players before they make a transfer offer to Mbappe.
back again, it's the problem of CR7's high salary that is preventing him from being attracted by many clubs, I'm sure if he wants to lower his salary then many clubs will queue
According to the report, there were two reasons why Newcastle did not want to transport Ronaldo. The first factor is the performance factor. Newcastle party assess Ronaldo's performance has decreased considerably. Besides that, the salary is too big for a 37-year-old player. So they don't want to take the risk of bringing it in.
I still think that such a high salary at such an old age is really a big bet for a club that is interested in him
