The retail magnate told Sky News that although talks were not yet at an "exclusive" stage, he hoped a deal could be agreed before the January transfer window.
The Toon Army will take Ashley's words with an Everest-sized amount of salt, with many viewing Ashley's "attempts" to sell Newcastle a year ago as simply being a ploy to detract from his poor running of the club and to prevent him from spending in the January transfer window.
Ashley, who bought Newcastle in 2007, has officially been looking to sell the club since October 2017.
However, the Sports Direct owner has claimed he would like to sell Newcastle before January, meaning a new buyer could provide Rafael Benitez with funds to spend in the upcoming transfer window.
The NUFC owner stating that talks with the potential buyer are way beyond any previous talks with anybody wanting to buy the club and that it is "possible" a deal could be done and dusted in December - but "realistic" for it to happen this month might be "too strong a word" to use.
Ashley has overseen a controversial decade-long ownership of Newcastle.
"Hopefully we can carry on the good form...just recent good form...and we can get the deal done".
Sections of the fanbase have regularly protested against Ashley and the running of the club during his eleven-year tenure at the helm and again made their feelings heard during Saturday's 3-0 defeat by West Ham.
The St. James's Park side looked prime candidates for relegation from the Premier League this season after a woeful start to the season.
They are now 15th in the table with 12 points from their opening 14 fixtures, and face Wolves at St James' on Sunday with protestors calling for a boycott of the televised match.
