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.
