You seem to be forgetting that we won have won today were it not for another outrageous referring decision. We've also deserved to win at Arsenal and Chelsea numerous times.
Your first part is right, it was a wrong decision by the referee and it should have counted, plain and simple.
That's not the full story though. Our performance generally was symptomatic of many, many away days against the teams I've mentioned.
Surely you can't use "we've deserved to win a few times" as a defence to our attitude shown in these games? Yes, we probably should have won some of those games. But that's my whole point. Close but no cigar, and that really sums us up at the moment. Quite good, not good enough.
I want better than that, and I think we are able to achieve better than that. Which is why I don't count today's performance as a good one. We didn't force the issue anywhere near enough, against a mediocre Liverpool side. Of course I'm disappointed by that.
