Simply- nope.
Walker having the armband is a microcosm of what this team is all about right now- past it, lost the plot, no hunger, and zero ability to impact a game when it needs to be picked up and dealt with.
Your captain should be a player who the other team looks over to and shudders.
I've not watched a City game in almost 10 years where I fully expected we'd lose by a hatful and we likely should and could have lost 7-0. At least a small part of that is because in past years there was a captain who would stick his boot up the arse of the other players when needed- maybe not Silva as much as Fern and Vinny- but he commanded respect. Walker doesn't have that anymore and should not be wearing the armband.
