The EPL defending champions have been linked with several players as the window approaches after a dismal start to the season.
Ahead of their match against Norwich, Mourinho was adamant his squad did not require an overhaul.
"I will not ask any change to the board for January," he said.
"I am happy with my players, I trust the players.
"I don’t need to clean the dressing room. And I don’t need to ask the club to spend money in January."
Meanwhile, Jose is expected to be in Chelsea's dug-out after completing his stadium ban in the defeat to Stoke City before the international break.
