Manchester City not linked yet with Lionel Messi indeed easy for signing him because have been free agent player, right now have Barcelona rumor will signing Lionel Messi but they can't pay higher salary and faced financial problem when registering Messi in main squad. Al Hilal have give fantastic offering for Lionel Messi but still not answer yet will accept or reject after not reach agreement extended contract with PSG. I want to see PSG make another negotiation how to make Lionel Messi want extended one or two years later contract with PSG and stay there for several years later. He has good and stable performance on every season with PSG and seems most disappointed if PSG have loss Messi next season.
It would be useless if Messi stayed at PSG, because PSG and their supporters no longer want Messi to be at PSG any longer. I think in this moment Messi might be better off leaving European Competitions just like Ronaldo and other stars have done before him too, because maybe Messi will have to decide to retire. Because, to be in a team with very competitive competition, of course it will be difficult for Messi who is required to give good results.
Unless the team only needs Messi as a senior player who can have a good impact on the team, then maybe staying at PSG and/or other big teams won't be a problem. Because the problem so far is that Messi is old but Messi is still required to be able to bring the team to many titles, so of course it is a difficult task to achieve.
