The Magpies are currently sitting in the bottom three after a poor first half to the campaign.
The Magpies have been in and around the bottom three all season, with their big spend on new players in the summer failing to turn around their fortunes.
They are currently 18th in the table with 17 points from 20 games, but are just two points from Swansea in 17th place.
It is fair to say that is has been a disappointing first season in charge for Steve McClaren at St James' Park, and now Mbemba has given his scathing assessment, labelling it a disaster from the start.
“At the beginning of the season I did not expect the team to be in this position,” the Mirror reports him saying.
"I don’t think any of the new players expected to be where we are. We had ambitions to be up in the top 10 at least but this season has been a failure right from the very start.
“We have to take all the responsibility. We have to give 100 per cent to make sure we turn this around.”
January is sure to be a big opportunity for the side, with them looking likely to add several new faces to try and turn their season around.
A big problem has been scoring goals; with the side only managing to score 19 goals in their 20 games so far.
That may force McClaren to seek out a striker in the January transfer window, as a proven goalscorer could be the difference between relegation and survival this season.
