Of course he should have shown it for the first team when he was 7 also. No? Then why is his 17 years at United relevant? He has done reasonably well for the first team (in spurts!) to be thought of as a squad player for future. That is all I am saying.
I haven't said he should have been brilliant from day one, but after 17 years of learning the trade here, if he was going to be a good enough player for us, he should have shown it by now other than a handful of good appearances. If he was 19 or 20 there'd be plenty of scope for improvement and not so much criticism, but he isn't.
I'd say even last season's performances were better than this season so don't see any progress there. This season in the games he has started our record is W7 D3 L2, without him starting it is W14 D3 L3.
This subsequent debate started because of the suggestion of the new salary and contract. We don't know whether it's true or not, but just if it was true it would make him unsellable and be paid higher than better players who are regular first teamers.
He should not be a starter, if he is willing to be a low paid squad player to make a few appearances off the bench and start a few cup games against lower opposition, then much less of a problem but he should never start ahead of Mkhi, Martial, Mata, Rashford or even Rooney in his position if at least two of those are available.
Any of those mentioned get on the ball and you're expecting them to try something, a dribble a cross, a surge into the box, something even if it doesn't come off.
Lingard gets on the ball and 8 or 9 times out of 10 he'll try the simple option, no risk which usually involves a pass backwards. Exactly what LVG seems to have brainwashed into him.
Remember Mourinho a month or two back mentioning that some members of the team needed adapt more to his style, I think Lingard's struggled the most although he has more freedom of movement, that hasn't led to him being more effective except the one cross he made to Zlatan which we'll be reminded about forever.
I hope he does brilliantly and proves me wrong, I have severe doubts but all I care about is the success of United
