I certainly dont think he is rubbish, but seeing what he can do and what he does on a weekly basis are very different things.
Perhaps its my inner Roy Keane or Fergie, I still have a certain expectation of how United players should behave off the field, maybe you might not agree with this but we never had super - flash players in our squad. Beckham & Ronaldo were two of the worlds best and consistent.
It seems the culture has changed under Mourinho, im not blaming him.
I remember also Rooney telling a story of Depay being out of the team, and was picked for a reserve match, and showed up in a Bugatti wearing snakeskin boots and a cowboy hat and he just knew he was a lost cause. I get hints of this from Lingard.
Maybe I am out of touch, but Lingard is 25 now and should be reaching his peak years soon. I know certainly if I was the manager I would ban all that social media dancing nonsense the lads do in the dressing room anyway.
The reality is, players these days spend far more time of every day of every week on football related issues than what they did back when Keane was here.
20-30 years ago, they'd play a game, then pop down the nearest pub and get drunk off their heads that night. They'd turn up to training the next day hungover or even still drunk. Very few focused on physical fitness outside of the training they did with the club. They could generally do whatever they wanted.
Nowdays the majority of them spend a huge amount of time focusing on health and fitness even outside of the club. Their diets are all planned out, they do extra fitness training and gym sessions. Very few of them drink or smoke. They also have far less ability to just go out and act like a normal person because of the celebrity focus that our society now has where the media follow them around looking for the tiniest little thing to attack them for, or the general public will be chasing them around for photos and autographs, etc.
If the worst they are doing now is dancing and having fun for social media, who really cares? As long as it doesn't actually effect their performances or go to their head (which it perhaps did with Depay) it's honestly much more professional than Keane and most of his generation was doing. We just didn't get to see much of that so it was the classic 'out of sight, out of mind'.
