That's not what I asked. Could the referee have gone over to the monitor of his own accord to check out what he was being told by the Chelsea players, without any invitation by The Complete and Utter one?Only if Dean thought it was a red card. That is the big flaw with the system - if it had happened at the corner they scored, it would have been a foul. But because it resulted in a corner, he can only refer him for a red card review.
