The Magpies' recent appointment of John Carver, who will be placed in charge until the summer, has been greeted with widespread derision by the club's fans who say it lacks ambition.
However, Charnley refutes these claims and he believes that the Magpies can still complete the initial aim that was set for them at the start of the year.
"Our goal for the season of a minimum top-10 finish remains unchanged, and we are confident that John, supported by the backroom staff, will be able to deliver this," he said to the Sunderland Echo.
Despite Charnley's optimistic words, Newcastle supporters are furious with the appointment of such an inexperienced boss.
Carver has never managed a team in England before and there are concerns about where the season will head under his guidance.
The 50-year-old did not win a match during his time in temporary charge and if this form does not improve after his official appointment the North East outfit could be dragged into a relegation fight.
Newcastle are currently eight points above the bottom three, but a series of losses would force them down the table and it does not seem beyond the realms of possibility that the worst could happen.
