Admittedly, I was at the other end of the pitch but I didn't think it was a penalty. And nobody around me got agitated about it.
Thankfully, the rules on hand ball have changed this season so they're not being given when a ball is hit against an arm at pace from a short distance. That's what appeared to happen in this case.
You can look at still images all you like but it happened very fast and it was impossible to remove the arm so it wasn't even much of a decision to make in my opinion.
I'll see if it gets a mention in the VAR review tomorrow and post the expert opinion.
