It's been rumoured that Manchester City or PSG will sign Lionel Messi soon. But I've seen this news today:
https://www.bbc.com/sport/football/58114039Guardiola says that Messi is not in their thoughts now. He thought that Messi would stay at Barcelona. They signed Jack Grealish and gave the number 10 to him. So, it looks like we may not see Messi at City. PSG seem to be closer to sign him very soon. As they have Neymar and Mbappe also, they will be the deadliest trio surely.
Guardiola signed Jack Grealish a few days ago. Now they don't seem to be thinking of taking Messi to the team. Manchester City will have to spend a lot of money to get Messi in the team, Manchester City may not spend that much extra money at the moment. Messi's next destination is most likely to be PSG. Because there is no shortage of money of PSG. But as far as it seems, Messi will decide to stay in Barcelona at the last moment.
Staying at Barcelona? There is no way for it. Haven't you seen that Barcelona are not able to sign Messi because of having a bad financial condition. And the offer they were preparing to make was against La Liga's structures. So this means there is no way that Barcelona can sign Messi now.
So, we should focus on which team he will go to. City or PSG?
