I agree that if you concede 6, you deserve to lose. But if a ref takes away 3 goals (2 offsides, 1 pen) from one team in a game, you should lose your job. The linesman who gave city their offside goal and took away 2 non-offside goals away from us, should seriously be sacked and investigated for matchfixing, i'll give you that you can make a mistake once in awhile, but 3 big mistakes in one game? I would get sacked if did that at my job.
