Barcelona should be able to forget about the desire to bring Messi back, they have been able to play well without Messi. Barcelona must pay attention to focus on getting new players who have good skills with those who are much younger. however, the Messi era is almost ended becaus of his age. If Barcelona insist on signing Messi and sacrifice financial problems, I think the Club will have more serious financial problems. After all, if Messi wants to support the club, he should be willing to be paid cheaply even though he is currently a star player.
If you think about it, it's true, Barcelona will only be wasting money if they keep insisting on returning Messi, because if you look at it from the other side, Messi has reached an old age which will affect his performance in playing, and apart from that from a financial perspective, Barcelona will also be disrupted. I think it's better to look for another high-quality player who is at least on par with Messi and definitely younger because Barcelona needs players for the long term. Barcelona must think about this before it's too late, and recently I've heard rumors that Barcelona is ready to pay Messi a high nominal if Messi can come back. I can't imagine if this is actually going to happen.
