This fact cannot be avoided, but as long as Barcelona can allocate each portion and also do the right goals, I think it will produce something sweet. Sometimes we can't criticize a team with bad finances like the one faced by Barcelona and indeed they can't buy star players like some of Europe's top teams.
I think the transition to talented young players or players who are more mature from that experience is good enough for future development. Now barcelona may be challenged whether they can return these financial problems to a stable point so that we will also see barcelona will compete with other European teams in fighting for star players.
Finances are still an issue at Barcelona and they can't afford to buy a star player for next season. The transition since Xavi took charge of Barcelona has relied on young players, but they cannot fully expect to compete with other teams using the strengths of young players. That's why they are trying to buy players like Gundogan to complement their strengths and maximize young players for the long term.
If you look at the current condition of the Barcelona team, it seems to me that they will find it a little difficult to face other teams in the Champions League and the youth strength they have is not fully ready to face other teams under pressure. The strength of the young players they have is not fully ready to face other teams, especially in the Champions League the pressure to play will be different from that in La Liga, so the strength of the young players they have is not fully ready.
This might change quite a bit with the addition of Gundogan who brings in all the experience necessary to compete in the Champions League. He is also a few years younger although Barcelona isn't really adding strength to their squad. Busquets left, Gundogan joined. They are now considering a swap of de Jong for Silva from Manchester City. This would mean de Jong is gone, Silva is added. There is still no significant change that makes the team fundamentally better. They have a good center line from the offense with Lewandowski via Gundogan in the midfield and ter Stegen in the back. But is it quite the same as it was last season despite some names that will have changed when the new season starts.
