Well I get plenty of them, using the official DB.
And I find plenty of players developping well by simulating just as use playable leagues.
Well, to be fair, I use a somewhat modified DB, so that probably has some effect when it comes to future years.
As SI has stated, that the game will keep the standard/reputation of leagues and level of players the same that it was in the opening DB. This also affect the transfers, so that many players will be transferred to the league to keep it's average player CA near the same that it was in the opening DB. And the changes in reputation and player level in the leagues will be very slow, alas change takes decades.
So if the average starting level England DB player has CA of 150 and the game has e.g 25 such players, the game will generate that amount of regens in the future as well, so that CA can be maintained. And if Brazil has similar amount at the start, but Brazilian league is not playable, more of those Brazilian regens will be created in playable leagues.
At least this is how it was before, I haven't played many long term saves in FM23, so maybe it has changed in that version, although I have not seen any posts indicating such change at FM forums or elsewhere.
Well, this post is largely off-topic, so let's just say that I fancy France over England. But England has good attacking players too, so hopefully there will plenty of goals in that match.
