leicester player feels a touch, dives and gets sent off
That's ridiculous to say that Vardy "felt a touch". He deliberately dived into the path of the defender causing their legs to tangle.
Credit where it's due and the ref got that one spot on where others would have bottled it and given a pen to the home team. Also credit for having the balls to follow up the warnings by giving a pen on Morgan, against the home team again. Unfortunately he made a woeful decision at the end under the pressure of the crowd but the Huth one could easily been given so perhaps that evened out a bit.
As many have pointed out, in all four penalty appeals you had players throwing themselves to the ground unnecessarily so perhaps they should be the focus of people's ire rather than a ref trying to do his best and judge whether they were cheating or not.
