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.
Let's see, but I don't think this is a good move. Messi has aged, he is useless for the long term. Barcelona should be more realistic with long-term options. In addition, they have spent a lot of money for this season. High salaries will probably put more pressure on Barcelona's finances. In addition, I once read they have a fifteen-year-old child who looks like Messi. Lamine Yamal has a record that exceeds Messi. He successfully trained with the Barcelona senior team at the age of fifteen.
The possibility that Barcelona wants to bring Messi back aims only at the money that Messi's big name will generate and we cannot change that fact because Messi is a Barcelona legend and also one of the GOATs of football. But if Messi rejects Barcelona's offer, that's very good because he can actually try new challenges in other top European leagues to add to his individual record.
On the other hand, if for the long term it is clear that it will not be able to fully influence the team and Barcelona should prioritize more young players for the next generation. I heard the name Lamine Yamal and it's true he is currently in the process of being promoted to the barcelona senior team at a very young age of 15 years. I think Barcelona must be able to provide space for their academy players to be able to give birth to the next football stars in the future.
