Relax no other club can afford his wages. Even the oil and billionaire backed clubs can't unless they violate FFP and other wage limits.
FFP? If Messi wants to join PSG he can do it, Nasser will find a way since he has UEFA in his pocket so to speak. I think Messi is thinking about his legacy and about retirement at this stage, about the stability of his family. His personality is different to that of guys like Cristiano or Ibrahimovic.
Why dent a perfect story by going to that club at 35? To prove what? There is nothing more to prove except winning a World Cup. PSG are dead on favorites to win the next CL looking at the deals they've made.
Mbappe, Neymar, Di Maria, and now they finally woke up and added defensive and midfield quality. Ramos, Donnaruma, Hakimi, Gini are outrageously good signings exactly in the weak areas (except GK).
