Barcelona won this league and this can be a great achievement for Xavi and his players especially when we know Xavi won the season while didn't have a good financial situation compared to Real Madrid. Barcelona also failed to hire Messi, I think Barcelona will have problems for the next season because they don't have enough good players and they need to hire many players at least they need to hire a forward to have a young alternative for Lewandowski.
Yes, you are right that next season Barcelona will have difficulty getting new players who are stronger, while Barcelona's finances are currently very chaotic.
But let's see if Barcelona's management will raise their voice on this issue and immediately follow up on financial issues that must immediately carry out player transfers to strengthen Barcelona.
If not, I doubt if in the next season Barcelona will not be able to compete with Real Madrid.
It is very likely that next season Barcelona will face obstacles because there has been no movement that has reportedly succeeded in strengthening existing players, in contrast to Real Madrid who have succeeded in bringing in one of the midfielders who will strengthen the existing squad, it is quite strange to see Barcelona continue to be in trouble financially so that it will be detrimental to the current team.
But that doesn't mean they won't be able to compete with Real Madrid or other teams, but the difficulties will be very different, if Xavi is able to maximize the existing players they will certainly be highly valued but clubs who always want to be competitive will be aggressive in the transfer market while Barcelona is constrained by that, very unfortunate and certainly not what the players expected.
