The Magpies have suffered a dire run of results every since Alan Pardew left to join Crystal Palace, and they are still waiting for their first league win of the new campaign.
However, McClaren insists that he is not under pressure at the moment, because Newcastle's managing director, Charnley, has always told him that the club will be patient with him, during their regular conversations.
“I don’t speak to Mike [Ashley]. It’s Lee Charnley’s who I speak to," McClaren revealed.
“We’ve spoken from day one about this. In fact he has probably stressed it more than I did about how much it would take, and about how much time it would take.
“He said ‘This is a job for an experienced person’, and that’s why we’re here. We’ve got an experienced staff who can cope with this and deal with this.
“Will it turn around over night? No. But there’s a reality from everybody looking that that’s where we are and it’s up to us now, it’s our responsibility now to turn that around.”
Newcastle have made improvements in recent weeks, but they have had little reward from their matches against Chelsea and Manchester City, with their fragility on display for all to see.
Newcastle had led Chelsea 2-0, but they conceded twice late on to let all three points slip.
Then, at the Etihad Stadium, they had dominated for large parts of the first-half, but when City got their first, another five goals followed within the space of 20 minutes and they collapsed to lose 6-1.
It is this lack of spirit which has plagued Newcastle for too long, and McClaren has a tough job trying to turn their attitude around.
Newcastle are currently bottom of the Premier League, having picked up just three points from their opening eight games.
