What was the ref thinking?

Orlando City star Kaka has been sent off after harmlessly touching the face of former team-mate Aurelien Collin. Watching videos like this makes you question the though process of some football referees.

To make matters worse, the red card was decided by the new VAR system.

A bit of argy-bargy broke out in stoppage time between Orlando and New York Red Bulls players. However apparently the worst offense was Kaka having some fun with his friend Collin. 

The footage below shows Collin protesting Kaka’s innocence to the referee, but he was having none of it!
