People aren't patient enough these days to give a youngster a chance.
You're either good enough straight away or they think you're rubbish and shouldn't be in the team. Look at Mctominay, many wrote him off straight away (myself included) but he looks a different player these days.
Garner isn't ready for first team football yet. Better to let him play the cup matches against Rotherham and some Europa league performances.
Next year he'll be 19 and more first team ready.
I also wrote him off which I am not now, but same token I am not writing him in either yet. Very good performance against PSG, a couple of other good performances and a good preseason. Suddenly in many peoples eyes he seems to have gone from shite to a quality central midfielder starting for us after a handful of games includign a couple of very good performances. Im certainly yet to be convinced he is the answer to our midfield, hope he does convince as always good to see our own youth players make it, but even for us, top top players from he youth side is pretty rare.
I wouldnt be surprised if he goes the same way as Lingard, looked like he wouldnt make it, improves, actually does quite well but never to the desired level which in time turns into derisory comments. I feel much like I see Lingard, he can become a very good squadplayer, also like Lingard not sure he should be starting game so regularly though.
Think partly as we have been so poor on the pitch and in the transfer marker we are desperate for youngsters to break though and over hyping many. Rashford I never saw as the star player he was painted out to be from his stack of goals early on, think he is an exciting player but still dont think consistently he is a top level striker at all. McTominay similar, Chong too, Pereira I actually had more hope for ironically. But for me none of these are players that are going to win us league titles.
On the positive side, ability wise I DO see that in Tuanzabe to a degree and certainly ability wise in Gomes and Greenwood. Seen little of Garner and its way too early to prefict, but looks a player there too....but come on games this season, maybe the fleeting appearnce, but even with the lack of genuine quality in our midfield its way way too early to expect too much for him, it is a position needs a lot of discipline and intelligence that comes with experience too, think strikers, wingers and thelike its a bit easier to break thorugh at a young age
PS The games this season was in answer to the thread not you personally. I agree with waht you are saying, though I dont see it personally, individually in the three ex-youth players that are playing in the first team already.
