I don't have an issue with the principal of VAR but in football there always needs to be a consistent application of the rules. We needed VAR because there were dubious offside decisions and blatant failures regarding penalty awards. The system hasn't changed that. I also thought united's goal at the weekend should have been ruled out. It hit the guys arm and went in. It looks like VAR determined that Brighton had enough opportunity to and as it came of Mac Allister and went in they allowed it - it didn't go straight in off the arm. But the fact is it hit the arm before the Brighton scramble which led to the OG.
The rules, for me, need to be completely clarified to cover these controversial situations. Personally, I think context is critical with giving a pen for handball. In the Dias case, it shouldn't be a pen as he was jumping and his arms were in a natural position - the ball was also going nowhere. The trouble is, things start to get very complicated and VAR will struggle to have consistency if you bring in caveats for rules.
