McClaren arrived at St James' Park in the summer tasked with shaking off the form of a previous campaign that nearly saw them relegated to the Championship.
A last-day victory over West Ham United spared the club from the ignominy of a second relegation in five years, and McClaren's appointment was generally greeted with widespread positivity by those connected with the club - but the reality has seen the former England coach begin life with the Toon in nightmare fashion.
Two points from six games represents a dismal beginning to life at St James' Park for McClaren, and the low point of his brief stint in charge so far came on Wednesday evening when they were dumped out of the League Cup after a 1-0 home reverse to Sheffield Wednesday.
Newcastle were booed off by their own fans after the defeat to the Championship outfit, and a damning stat has revealed just how poor a start it has been from McClaren this term.
Five defeats and two draws from his first eight games in charge has seen McClaren claim a win percentage of just 14% - leaving him with lowest rate of all of the club's last six managers.
The record is perhaps made even worse when you consider that the list includes the likes of Joe Kinnear, Alan Shearer and John Carver, and speaking after the defeat to Wednesday, McClaren admitted that it was close to crisis point at St James' Park.
"Is the job harder than I thought? Absolutely. Without a doubt," he told BBC reporters after the game. "People say it's a crisis and it's getting very close to it. We deserve to be criticised.
"The only people who can do anything about it are in that dressing room. We have to be fighters, not victims. How far do you go down before you turn it around? Do you say that's enough?
"For me, that's enough. We need results. There is trepidation but it's a great game for us on Saturday. I have been in football too long to be embarrassed. Angry, disappointed. Things like that can happen in football.
"The booing? Deservedly so. That is what happens when you lose games you should win, and don’t score goals. You have to ride the lot, deservedly so.
"No excuses. The criticism since West Ham has affected us. Confidence is draining out and we can’t have that. We have to draw a line in the sand. We said to the players you can feel sorry for yourselves or you can come out on Saturday and be a fighter or a victim.”
