He's 16.
And from what you have said little belief in their ability to shine.
And 16 is a great age to think 'will i be getting a chance to play football by the time I'm 18', which is only a year and a half way. Bear in mind most high, high level footballers are playing football at 18 latest.
I think it's a very narrow-minded view to say they have no belief in themselves. It's the exact opposite in some cases. They have extreme belief in themselves, jsut don't believe in the club. Would I say you had no belief in yourself if you left your job for career prospects somewhere else? Imagine you saw all your mates and colleagues being told for years that if they worked hard, ticked all the boxes, improved their performances then they were inline for a promotion...but it never happened, for any of them, ever. Would you sit wilfully on your arse hoping for a miracle or would you be proactive and go somewhere else to learn more things? Is that unambitious? Is it fuck. You're saying that cos they're leaving the club you support.
Brahim Diaz is 18 now and arguably one of the brightest young players in world football, coveted by everyone, but he's already starting to look like he's set for the 'fuck off to various clubs on loan for 3 years' route as there is simply no chance for him to get more than a couple of sub appearances. It really, really pains me, cos he's clearly immensely talented as he showed in preseason/in countless youth games, but he's never gonna get the chances he needs to develop apart from some scatty loans? If I was him I'd just fuck off permanently and make my way up from a smaller club. It's a shame, so I really don't blame the kids for starting to have their heads turned.
I can't think of many if any 17/18 year old players involved regularly in premier match day squads do not sure what these kids want. Take Tammy Abraham who has been out on loan in lower leagues done well then comes back to his paren club and is loaned out again to a club in a higher league now here he is playing for England. Get your heads down and if you do well success will follow. Plenty of kids have left City and gone on to do absolutely nothing at top level...
You're totally right, there isn't many, but that's a very recent phenomenon, and it isn't a good thing. There isn't many young English lads at 20 either, never mind 18. You can't use that as proof that they're being impatient, as that's actually the reason why they are getting worried. The Premier League is totally fucking awful at using young English lads. It's a highly publicised problem, one that many discuss often. Clubs just have too much money and don't bother developing and instead sign loads of players instead. City and Chelsea are sadly two of the worst at this. They also, ironically, have the best talent.
I'm a lifelong City fan. Immensely proud and confident in my abilities too, but if I was a young lad at City i'd be tempted to stay there until I was 16, assess the options, see if there is any precedent for young lads getting a chance (their currently isn't, for whatever the reason) and then move to a club where I think I could actually be playing if there was no clear pathway.
