Vardy has got to play. I don't base that on any sentimental judgement, purely that any poor spell when you are approaching mid-thirties is deemed to be decline. Vardy being a late starter and a person who still looks lean and hungry to me, still has plenty to offer
I personally believe Vardy has struggled with an injury niggle for a while. This as coincided with a barren spell. Vardy imo is still quick and certainly a clever footballer.
Recently he looks like a player who as become a bit anxious about the lack of goals and consequently become snatchy.
The Man City game was no game to judge Vardy, such was Man City's control over us he virtually had fuck all to work with.
The off the ball running is vital also, Vardy also emits a powerful reputation which attracts close attention, leaving space for others to exploit.
No doubt Vardy needs a goal, he will get it very soon and when he does his confidence will be back and I would expect the bandwagon to roll again.
Don't write him off, I am still glad he wears our shirt rather than an opponent
