How do you know they are not good enough? To my knowledge they not been tested.
As many already more then well laid out, the reason Inter hasn’t produced good enough players is because the development stops at the crucial stage. Far from all players have the magical combination of high raw talent and mentality to break through on their own they need the proper help and guidance. This is something other clubs outside Italy is starting to understand and that is understood to much higher degree in other sports.
There been massive criticism of how we deal with talents, from players experienced other systems, how they where left alone, wasn’t helped etc. leading them to give up and move elsewhere, in some cases stopping all together.
The mentality and over evaluation of experience is a mentally that needs to change, there reasons why the NT ain’t any better. Italy youth NT are doing fine so are ours at young age but once we hit that crucial stage things fall apart because of the mentality that exists in Italy. It’s not a good idea to throw young people around once every year on one loan after another every one who ever dealt with young people and helping them grow would tell you this. To get the best out of them you need to be constantly in touch with them and their development most other sports figured this out years ago. Personally I hope UEFA/FiFA put an end to this madness and ban this practice all together. Personally I still dream of ban against loaning players under the age of 20, that clubs throughout all ranks max can loan out 3 players.
