I actually work with people, different ages, backgrounds, nationalities etc. I'm in management for a US company that sees yearly overturn of about 15m on average.
My job has taken me to work with different profile of people, graphic designers, software developers, admin, HR, Sales etc.
One of the assumptions that I had for every employee was that you can manage him into making him a good employee who can raise through the ranks. We had bad hires at times. Lazy, late, arogant. I had to learn quickly how to manage such employees as I always assumed that there is agood worker there no matter what, up until one day, the owner of the company pulled me to the side and asked me why I'm I trying so hard with a specific employee. He told me a saying that I see daily application for. You can bring the horse to the water, but you can't make him drink.
Now, I totally understand that a simple employee which you can replace much easer than 73m asset that has valid 5 year contract on 300k a week are nowhere near similar In comparison. What I truly think is that Sancho is missing life in Germany.
You mentioned that Dortmund got the best of him. Well, he had the same issues in Dortmund as well, one being late. The reasons that I can think of why Dortmund was not making fuss about it were
- He is an asset that they had to increase the cost to in order to get the most money possible
- They had to keep him happy in order for him to play at the level he did
- Keeping his tardiness hash-hash meant no bad media coverage
Fast forward to United, where everything is public and the people that were turning a blind eye to his indiscipline are no longer there. It could've ended only in one way.
Granting him special privileges like he is a primadona, I truly believe would not paint the club in a good way, especially since Sancho has not performed well since he got here. You are opening the door for everyone else to act the same as him or to drop performance levels if they don't get the treatment like him. I truly want him gone, he is too arrogant to be properly coached, and he believes his own hype. Let's not forget that he failed in England shirt as well.
To circle back to my point, he likes it in Germany, rules are loosened for him, no media pressure, and his bad games goes without notice, as everyone was talking about Bayern.
