Perhaps the regression is compounded because, as you say, two years ago he was virtually unplayable and didn't try to stand his man up?
For whatever reason, he doesn't seemingly trust that directness anymore, so he is giving defenders more opportunity to expose his lack of technique and decision making?
The saying form is temporary, class is permanent, is well known, yet Raheem never gets injured and has already had a career of games most 30 year-olds would be proud to boast of.
I have assumed for a while he could play his way out of this funk, but I am concerned he either needs a fresh start somewhere else, or he has peaked.
The worry is, he exhibits the same issues for England, in terms of general paucity in his play, so it must feel like a delicate balancing act for City at this juncture in his career?
