You seriously think Maguire dictates how we play ? And as a CB he would have more 'overview' ?
A captain is there to lead by example, to encourage his teammates and to bollock the ones who slack. A midfielder is there to dictate the tempo, like Scholes. Even he was no captain. It's two different jobs.
And no, you do promote your best employee to a management position if he or she has adequate management and leadership skills. It's rather you don't promote someone with an average performance over your best performed employee. If you do so a lot of eyebrows would raise imo. What others and your best employee would think? Is is fair?
Well I didn't say anything about Maguire on purpose. As in maybe the best Captain in the future isn't even at the club right now.
I just said I don't think Bruno is a good fit, at least not yet. But of the two I think Maguire is the better choice yeah. Is he perfect? Absolutely not, but from what I've seen of him in half a season so far is lightyears ahead of what we've had since Rooney. At least Maguire plays matches. I think Maguire can grow to become an even more solid Captain over time. But at least we now have several leadership characters in our team, something we've lacked for a long time.
Yes I do believe that Maguire is dictating the defense at least. But still needs to improve and our players need more experience. He has time to see a lot more of what the opponents are doing in a bigger picture compared to Bruno who is looking for tight spaces to exploit.
You definitely do not promote your most skilled workers to management, only exception could be if you feel they would walk if not. Going too far with this comparison isn't totally fitting with the Captaincy role in football, but being in management takes away a lot of time from actually producing work. If say you are a skilled artist you want them to spend time drawing, not doing paperwork. Most super skilled workers want to focus on that as well, to excel at their craft, not be bogged down with management duties.
