Perhaps the endless whining about finishing 4th and not winning a trophy in the first year of this new project might suggest the fanbase isn’t particularly patient with building a long term project around younger players.
Case in point is Kulusevski. Fan base has zero patience and interest in the growing pains of developing young talents. Couple months of bad form and they are instantly seen as persona non grata. And these are allways the same fans who cry for young talents every transfer window.
I read just couple weeks ago people giving up on Vlahovic saying Amauri was better. That the 23 year old Locatelli had a bad first season etc.
And these two are the top choice success cases and signings, getting this much toxicity.
Every young signing who is raw a bit or stutters a little in his development will instantly be given the Kulusevski treatment of pure hatred.
While he is showing in EPL that there's nothing wrong with his talent. Just lacked patience and right way to fit him in to grow properly. But generally as said, most here just pay lip service to the idea of signing more young talents. They aren't not there for the reality of it.
In general just zero patience with young players despite the constant lip service and excitement for signing them.
