Agree with this, disagree with you on the ref. Offside was marginal, I think his body was offside, but can't blame the AR for not making the call when it is that close.
Berisha and Brown in the first half wasn't a penalty (assuming that is the one you are talking about), just a tangle of legs, and Berisha didn't claim a penalty and helped Brown up. I don't think Durante's one was a penalty either, was a shoulder to shoulder challenge to me.
I'm still pretty certain (but not 100% as I don't have 'smoking gun' replay) is that it wasn't offside. The best shot I could find is Berisha half a stride in fron of Durante, with the ball some well in the air already. From the shot, it's clear Berisha is in full stride, Durante at best is flat-footed, at worst has just stepped up. Extrapolating the situation to the moment the ball was passed, I'd say at worst Berisha was level with Durante, therefore not offside. But like I said, I've had a hard time finding a really good replay I could pause at the time the ball was passed.
Interestingly, in the TWs game earlier in the day, Musa made an almost identical challenge on Slefendorfas, penalty and a yellow card, and not a single soul at the ground grumbled about it. Durante's challenge I certainly didn't see as a shoulder to shoulder, it was pretty much a full body charge/check which is legal in ice hockey, but not in football.
Not sure if you have seen the replay yet, but at the time I rewound it on mysky and paused it on the frame when the ball was hit - it looked like, as I said, the feet were on, but the body was off. The AR looked to be a couple of metres out of position aswell.
I went back because I was fuming as I thought it was well off, but felt better after pausing it as it looked so close I couldn't really complain.
