The history will not repeat again. I think that you shall forget it and then move on. The new era has begun. Messi has gone to the PSG and he was also become even older. There's no choice rather than giving the young talented player so many chances.
Barcelona needs to do more regeneration but it will not find the player like messi again. Messi was messi. There will be no another messi to come.
Agree with what you say, instead of continuing to hope for the golden era and talking about Messi, it's actually better for Barcelona to start a New Era because even though Messi is now there, it's still not necessarily able to lift Barcelona's performance and become a focus like previous seasons considering his age. now the main problem.
They should focus on making new history rather than constantly looking to the past.
