It looks like Laporta is still thinking about making Messi come back to his old team sooner or later. Maybe he wants Messi to end his career at Barcelona by playing his last matches there. I don't know whether this can really happen in the future. But it seems clear that they won't make any offer for him before this transfer window ends. They had better not to also because their finance is going even worse as long as they continue to bring new players.
Xavi indeed want Messi return to Barcelona because he still consider Messi is great player but he said only if Messi contract ended which mean on 2023 not this summer but i don't think PSG won't let he leave even in the near future PSG have a plan to extended his contract because although his performance not so good last season but in the term of economic income Messi effect really successfully to get more sponsorship for PSG
Messi is 35 years old at the moment and for Barcelona's plans next season to bring Messi back to Camp Nou after his contract with PSG expires, I think we will have to see how Messi plays this season with PSG and I am not sure Barcelona will realize their plans if Messi's form continues decreased with PSG and also for players who are 35 years old, of course their performance is not optimal anymore.
these are just rumors and wishes from the Barcelona management and we don't know what will happen in the future, and personally I'm a little doubtful about Messi's performances that are declining with age.
Barcelona still feels very dependent on Messi, that's not good in my opinion. After all, no player is bigger than the team. They have to quickly forget their success with Messi, because players won't be on the pitch forever. They have to depend on the team, meaning the more influential team here. Don't let them depend on one player, whoever it is.
It is true that a team should not be too dependent on one player, it will harm the team. Because a professional football player's career is
not long, so when team depend on one player, when that player moves to another team or retires, the team's performance will be affected.
I remember the previous season when Messi decided not to renew his contract at Barcelona, then Barcelona's performance at the start of
the season was very bad playing without Messi. After Barcelona managed to bring in Xavi as coach, then Xavi can make Barcelona slowly
escape from the shadow of Messi.
It doesn't really matter if Messi's contract runs out with PSG, then Messi decides to rejoin Barcelona, it will motivate other Barcelona players,
because Messi is a Barcelona legend. But that doesn't mean Barcelona's game will be centered on Messi anymore, like you said after all the player
can't be bigger than the team. If Messi were to rejoin Barcelona, Messi must not be selfish as a star player, he must be willing to adapt to
the new Barcelona style of play, not Barcelona changing their style of play to suit Messi.
