Chelsea asked for a penalty for handball ref declined went to VAR they agreed with ref, no penalty, later on motd it was a conclusive penalty, how ever given that the ref gave us a free kick would
make you 100% certain of a penalty, I'm still not sure they would over rule.
Just as an after thought it was also said on motd that all the decisions so far with VAR have been to cancel goals not once to go in favour of the attacking side, this was a couple of weeks back
so stats could have changed.
It's not so much I don't think VAR could and should have given a penalty but the people using it.
