I just watched the goals/non-goals back, I think mostly the decisions are correct. The obstruction of Barry seemed questionable, but I'm not sure what the rule is there anymore in terms of "blocking" the keeper. Mignolet didn't try and go around Barry. I don't know if Barry needs to be trying to play the ball somehow though, but Barry just seemed like he was standing his ground rather than backing into the keeper.
I still resent the Salah type penalty though as yes the defender tugged him but he went down theatrically which was no different to the Niasse situation.
They need to get much quicker at VAR though.
Also funny they're still looking dodgy at the back, particularly on set pieces today after their 75 mil signing.
