The ref has to take responsibility for the decisions though and should have been watching the ball. He shouldn't ref another game in this Division for 12 months imo.
I still think Chelsea would have won comfortably but I guess that's not your point.
In an idealistic world, the ref will have an eye on the ball at all times, he will also have 20|20 vision so he can see exact details from 50 yards away. But alas, we are in the real world, where **** just sometimes happens.
Same as our disallowed goal against West Brom last season, was that the ref's fault? He didn't make the call, the linesman did. So now should we castrate the ref for that? The ref is not responsible for the actions of others, just like I wouldn't be responsible for someone elses. Was it a mistake yes? Did the ref get it right? No, Why didn't he get it right, only they know, but based on what I seen, I can only imagine the linesman made a balls up, or neither actually seen what happens, and you can't call something that you haven't seen, its a lapse, but not something I feel should be punished. Not the ref anyway, linesman at most.
Do I feel bad for Cardiff, of course, stuff has happened to us too, but if neither has seen it, then its not an instance that was really badly handled, like calling a goal that didn't actually go the right side of the post (reading? i think?) or calling on-side, when the player is 5 yards offisde, or on-side for that matter. More a mistake, however if the linesman did see it and called it wrong, then it is a balls up of the highest order, but still the ref is not the one who should be blamed.
Sometimes mistakes are made, after all ref's and linesmen are human beings, we all make mistakes, some of us have no doubt crept over the speed limit without noticing, but do we get punished for that everytime?
As in all thingss, **** just sometimes happens, and there is not a great deal you can do about it. And whilst referee's and linesman are human beings, mistakes will always happen, some worse than others, and in this instance, if the linesman has called it wrong, then he needs to learn, but to blame the ref, who didn't see it, is for me, just morally wrong.
Put it this way, the ref is running backwards at a fair pace, in a blink of an eye, or the moment he takes a quick look to see where he is going, the incident happens, what are we expecting here really?
