To summarize, McKenna had been at United far longer than Ole, you said it yourself that he was here when Jose was manager. So lets use that as the baseline to judge his overall performance. Its not about he stayed when Jose left but more about the overall time he had spent at the club in his role.
The fact that he was not the manager but played a lesser role (although still within a huge significance) doesnt mean that he should be hiding behind the manager's failure. Would you not agree with that? if someone is really exceptional even if his superior holds him back, at the very least dont fail at the basics. For someone reportedly to have an attacking minded approach with strong tactical knowledge, our players struggled with the basics and surely McKenna played a big part in that?
Again, the performances that you see week in week out, over a long period of time show it. So it's good that he gets a job as a manager now, I just dont know why some people seem so bothered that a few posters want him gone. Its logical in my opinion. I would want to keep him if he's only been here for a short time - second chance, benefit of the doubts and all that. I also dont think replacing him is that hard, again, look at how we played, did the players look like a bunch of strangers on the field? if so was it not down to coaching and tactics? if so, not only Ole was responsible but also McKenna and Carrick. Lets be fair here.
Was McKenna manager or Ole and Jose? How do you know what level of role he played?
Lets take Rangnick as example, do you think he will bring coaches to implement his philosophy or will bring coaches to implement their own philosophy?
Yes, McKenna and Carrick were first team coaches, doesn't mean they were the one who dictated the style or lack of it. They are hired to implement Ole's vision and how Ole wanted.
Also I don't get this "PR" thing and "hiding behind manager". Did he give any interview blaming Ole? Have you ever seen coaches getting shit like McKenna and Carrick got when manager failed?
Lets take Chelsea as example,
Joe Edwards - Appointed under Lampard
Barry - appointed under Lampard
Hilario - Appointed under Conte
Tuchel brought just 2 coaches. So are these coaches shit or world class. There are 2 versions of them, one under Lampard and one under Tuchel.
End of the day, it's the manager who is responsible for performances, team is always reflection of manager's vision. Not coaches'.
