The greatest thing about Barcelona getting this win isn't just football or fandom, but also financials as well. Real spends their money to get the best players in the world and build a 1+ billion dollar worth starting eleven, whereas Barcelona just gets their players from La Masia.
Honestly, La Masia is an insane youth academy, I think 7 players were from there, obviously someone should double check that, I just "know" but I trust my knowledge there, I do not have a proof, I didn't check all of them, but if I am not wrong they had 7 players from la Masia in the game. That is insane and they still managed to beat Real Madrid with ease, and destroyed Bayern Munich as well. They are looking like old Messi days Barcelona once again.
It must be admitted that Hansi Flick Barcelona is currently performing very impressively, unexpectedly they were able to beat Bayern Munich and Real Madrid with big scores. This success will certainly open the eyes of football fans, where expensive squads sometimes do not always guarantee victory. With these two big wins, Barcelona bargaining power in winning trophies in every competition has increased drastically, especially if they continue to perform consistently in the future. It is true, the majority of Barcelona players are currently products of the La Masia academy, as is known the financial crisis experienced by Barcelona opened the way for them to be promoted to the main team. Hansi Flick cool hand managed to encourage them to find the best form of play, and we also must not ignore Xavi previous role.
