My opinion, from the rumour mill, what Clattenburg has said himself and what we’ve seen publicly is that Clattenburg was treated poorly by Reily and Elleray. So I can understand his criticism of them from a professional standpoint.
The personal insults and comments on other referees personalities is a real shame in my opinion and comes across very immature - maybe the entire text will reveal more but it doesn’t sit well with me to have a sly personal jab at people who he knows get so much stick from the public (stick he bemoans when directed at himself) and for me he has just given another stick with which to beat them.
Clattenburg was a brilliant referee, the best I have ever seen and in my opinion the best in Europe for about 10 years, this is all rather sad.
