Of course, we are incapable of observation or independent thought. That's why it's so gratifying to receive advice from some random internet poster.
You can be sarcastic but a narrative was set by a couple of pundits - mainly Carragher - which was then repeated enough times for it to become accepted fact by not only other pundits and journalists (who I was actually mainly referring to) but our own fans as well.
In the Arsenal analysis Carragher actually blamed Yaya for not marking Ozil for the goal when mangala had just given the ball away. He quite rightly should have been nowhere near Ozil as we had the ball and he can't legislate for us giving it away.
But Carragher uses it to lazily compound the myth that Yaya is lazy and people swallow it hook, line and sinker.
Yaya isn't immune from criticism and he does have his faults but this idea that's he's lazy is just complete and utter bollocks.
Given all he has achieved in his career - that's before we even get onto what he has done for City (and continues to do - see yesterday) - then he deserves a bit more respect than being branded as lazy.
