Just read the report and in particular the last paragraph about the Rochdale penalty. I just caught the goals on ITV, and it wasn't Moxey who fouled the Dale player was it? And I'd say that the only difference between the severity of the two fouls was the fact that Harley was the last man, whereas for the Rochdale one, there were a number of players in the box.Report for the match, from the Rochdale site. Seem half the goals were offside, and the result not helped by poor and inconsistent refereeing.
