The most likely situation is that they aren’t and never will be good enough though. It sounds harsh but it’s true. Garner is a perfect example really, he’s much more experienced and highly rated but the truth he hasn’t actually shown anything at all to be excited about. This is top level football, it’s very different to doing reasonably well in the under 23s."Inexperience" is a BS excuse for players not being good enough.
With our current record we could have Messi and he'd never sniff the first team cuz he's "not ready". Then we wonder why every team around and abroad gets these good young players lol
So they get experience only when they're 20, never before then? If they never play, they never get experience, and you start somewhere.
