For all the half wits on here these are the laws of the game regarding red cards
SERIOUS FOUL PLAY
A tackle or challenge that endangers the safety of an opponent or uses excessive force or brutality must be sanctioned as serious foul play.
Any player who lunges at an opponent in challenging for the ball from the front, from the side or from behind using one or both legs, with excessive force or endangers the safety of an opponent is guilty of serious foul play.
For the past few seasons all we have heard about is when a player, making a tackle, has two feet off the ground he is out of control. Trippier lunged, from a distance, at KDB who was running a full tilt, both feet were off the ground, thus out of control and therefore was endangering the safety of the player. The challenge doesn't have to have excessive force. Once the red card had been shown we are then told about the high bar required for it to be overturned. The bar suddenly dropped to the ground as their is no cleat and obvious error made by the ref.
Did Trippier lunge? Yes
From the side? Yes
Out of control? Yes
Endangering the safety of the player? Given that contact was at knee height then the answer is more than likely, yes.
So where are the ground for an overturn. There are none so this debate should end now.
In rugby the ref and TMO would look at a red card incident and work through a framework to ensure the correct decision is made

I have just gone through the framework for football and still arrived at a red, there is no question in my mind that the ref made the correct decision in the first instance and was then 'persuaded' to change his mind. Have to protect the brand don't we, don't want little nasty City winning game after game. Utterly corrupt and not sure why people on here can't see it unless of course you are all WUM.
