No reason at all to hate him
I don't think he is good enough to be a regular player in any team good enough to challenge for major trophies.
That is United or any other.
Not being good enough is not a crime or a reason for hatred.
But a lack of effort or behaving like Mr Big, when you haven't earnt it, is an issue.
As some else suggested, not an unusual behaviour in the very young who get too much too soon.
But he is no longer a youngster, at 27 he is now the age of many senior players, but it is easy to think he is younger.
But at 27 he should be leading the way in our squad, I don't think that will ever happen.
None of us knows Lingard the person, he is probably a nice guy, but he is not the quality needed for a United team to fight for top honours.
I would be delighted one day to say I was wrong, but no sign of that in the last 12 months.
After saying all of that, he does not help himself at times, his videos, his clothing line etc, all would not be an issue if he was performing at the top level,
but becomes a burden and something to use against him when playing as he has for some time now.
Good luck, hope the rest of his career is as good as it can be, but don't think he is good enough for us.
