I am pretty sure that there is nobody in this forum who thought the team would go on and massively improve after a GOAT tier player, around whom the team had been built for at least a decade left us and no replacement was brought in. That would be just dumb.
But it's also pretty clear that with Messi there are issues which stem from his playing style. Not having to bother with those is a better ground for rebuilding. And it can (and should) start showing this season. Not with results (as nobody can bring what Messi did) but in playing patterns, pressing, defending, collective side of the game.
Having Messi here for one more season might give us a glimmer of hope that the title is within reach, but it's not much in the grand scheme of things.
So, losing Messi is a big blow, but opens certain possibilities which the team must take.
Agreed, As you say, the title may seem more within reach with Messi on, but mind you, still with a good possibility of failing to get it. The title appeared within reach in both last 2 seasons and we still imploded when we had to make our move due to various factors.
I would have been ok with this and with Messi leaving if we started this season with a coach who has a clear identity on the collective side like a Tuchel, Pep, Klopp, Flick, Nagelsmann.
Feel like Koeman is a manager who mostly relies on individuals without having a clear identity imo.
For me, the aspects that were mentioned will only happen when a new manager that Laporta really likes comes in.
Yeah, Koeman is good to a point. He's not the manager that would create a new team that's for sure, but he's good as a cleaner or in the incipient phase to man up these kids into more mature players, learning them to get used to the pressure and responsibility. Until someone with a better vision comes up and starts drawing this new team on the board.
Still, as fans, we have to accept that this is in fact year 1 into a proper clearly assumed rebuild. What we did so far up to this point was to try and still patch things up so we can snatch a title and postpone this moment, all piggybacking on Messi basically. Can't burns stages without some serious cash. We'll be in for a longer rebuild than we'd like, but the process can be nice and can have its perks.
