Sections of Newcastle fans have been appealing for Charnley to step down in his role, following their relegation.
However, it is reported by the Chronicle that Charnley has had a major role in keeping Benitez at St. James’ Park.
Benitez is expected to sign a new-three year contract at Newcastle in the coming days, after being convinced to stay on Tyneside.
Charnley has been the mastermind behind these discussions, after being left to it by owner Mike Ashley.
Benitez has regularly held meetings with Charnley, and the pair are believed to enjoy a good relationship.
Benitez now apparently feels that they can continue to develop this bond over the coming years.
If Benitez does commit his future to Newcastle, it will be a major boost for the North East side, as they aim to bounce straight back from relegation.
