There was a good quote from Bayern forum. Can't remember it correctly but they said they are surprised that Barca looks so much to buy players from outside when it's been proven over and over again that relying on Barca products works best.
Sticking to this is what makes us have one of the worst GK in top 5 leagues as backup to our Stegen who is injury prone.
Never mind it can force us to promote players earlier than needed, which in itself can be harmful to both the talents who got promoted earlier, or feel of unfulfillment with those who are late bloomers like Casado himself.
At the end of the day, we are aren't like Bilbao, a nationalist type of club who is very closed on itself. We buy talents from all over the globe and honestly, we are pretty damn good on it when we aren't careless. We bought a player from Croatian 2nd division and sold him for 10 times the price a year later.
Flick is showing no hesitation in trusting our academy, so if he says he need reinforcement in one position, I won't mind going for that.
For example, he prioritized Olmo over a CDM despite huge backlash from the fanbase and it is proving to be the right decision so far.
If he wants a LB, which it seems to be the truth, after showing no faith in Valle then I will trust his judgement tbh. So far he clearly doesn't rate him much.
Same for CB btw, he has tried both Cuenca and Dom with no success. If we lose one CB from the squad next summer, then I would trust them if they go for a new CB (I hope Mbacke will get a chance though, I would like to see how he fares at that level)
