Laporta's comments could be a moment of pride, trying to make Barcelona sound in a strong position but once a deal is agreed, its up to the player to say no rather than Laporta.
Even if we don't get De Jong, it is not doom and gloom as we have ample talent in the academy who can be bedded in. The existing squad does have the talent to compete at the top, only problem is that they suffered from a fitness and mentality breakdown last season. Like ETH said, this squad achieved 2nd in 20/21 which tells you something else happened. There are various tactics that ETH is capable of using and I am confident he can play different tactics that brings the best out of the squad's abilities.
Finally, stop being so negative. Success is not always guaranteed at a club but as fans, we must always support the club with optimism even if the entire squad is left with 16 year olds. You always hope that the club pulls through in all their matches, rather than supporting them only if they are dominant.
