It's better to just say that the elite talents in our system have a chance. If not elite, I likely don't believe they have much of a chance.
I never thought Gomes drifted in and out of games. His production for an attacker was great, it's just that he often had to step next to the CBs in order for the team to bring the ball out from the back.
I thought he did drift out of games during his initial step ups to the u18 (as a 15 year old), and to the u23s (as a 16 year old). But that's completely normal considering his age respective to the level. As a 16 year old, and as a 17 year old (after injury-u17World Cup), he did really well in the u18 and u23s.
So any problem was more so his teammates lack of quality by being unable to resist a press, or pass through lines. Something he was able to do.
Another key component was Sbragia being in charge of the u23s from 2017-2019.
