Yes, you are right if Barcelona wants to be a better team in the coming season, not only the attack line must be sharpened, but the defense line must also be strengthened to be even stronger. Because it is undeniable that there are times when Barcelona always concedes goals even against weak teams, even though in the end Barcelona wins, but of course it is quite vulnerable if playing against strong teams. So with this, Barcelona must strengthen its defense line too. Because next season other teams in La Liga or competing in the Champions League will definitely be much stronger. So to anticipate this, Barcelona must immediately strengthen its current defense line.

But until now I have not heard any news about this, I don't know what plans Barcelona will make, maybe because they are confident with their current defense line, or maybe not yet. Because currently the transfer market is indeed being disrupted by the World Cup between clubs, so with this maybe Barcelona will wait until the tournament is over. But if Barcelona does not bring in a quality defender, I think it is quite vulnerable for their squad. But what can be done, currently Barcelona must be having a headache calculating the budget, because as we know Barcelona's current financial condition has not really recovered. So with that, it is possible that Barcelona will not bring in a new defender.
