Man City is in the most favorable position to do this. Not only Pep Guardiola, Green Man also has Sergio Aguero in the squad and the club of the team also has CEO Ferran Soriano & CEO Txiki Begiristain, who worked with Pep at Barca previously.
Even the club coaching staff includes Rodolfo Borrell, who led Messi in the Barca youth team.
Meanwhile, Paris Saint-Germain’s chances are really not great. They are rich and have just had a season to reach the Champions League final, but there are disagreements at this club over a power competition between coach Thomas Tuchel and technical director Leonardo. Tuchel was not Guardiola, but PSG was busy resolving internal disputes, afraid Messi would not want to come.
And MU, the more difficult because even though they are also rich, their prospects are not really bright enough for Messi to want to join. Leo with limited English can work with Pep, Aguero and his Spanish countrymen at the club, but does he want to cooperate with Ole Gunnar Solskjaer? Not to mention the position of MU at this time is not equal to Barcelona, but Messi left Barca to find opportunities to compete for the title, not to go back.
As for other teams, people talked about the unbelievable prospect but dream Messi kicked with Cristiano Ronaldo at Juventus, but unbelievable is because the Serie A champion is bleeding money because of the salary of 30 million euros/year of CR7. Real Madrid is even more unbelievable because Messi is only hostile to Barca’s leadership
Messi’s ability to return to his hometown of Argentina is very low as he still wants to compete for the title. That is why the US, China and the Middle East are even more difficult, especially after China imposed a ceiling salary on foreign soldiers.
