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.
Real Madrid can add new ones to the transfer bombs that started with Bellingham. For example, very good names are spoken instead of Benzema, who left the team. Especially Harry Kane. Even without him, a great striker transfer could definitely happen. The strongest team of this year may be Real. Even Manchester City can't stop them if Mbappe joins the team.
Kane and Mbappe are probably good options for Madrid in their search for a replacement for Benzema. but it seems the current rumors are looking far away for Madrid to get both, or one of them.
Kane seems more interested in Man United. while Mbappe I don't think will leave PSG after they lost several important players in the squad.
Madrid must find another alternative if they do not want to be left behind by City. this season Madrid is lagging behind City and they have to catch up with several player transfers. if not next season City could have dominated again in Europe.
For Real Madrid, next year should be with a very good squad because they haven't won a trophy this year other than the Copa Del Rey. They had to leave the Champions League and La Liga to their rivals. They were subjected to a lot of criticism especially because of losing La Liga. They should definitely get a very good striker next year.
