Rummenigge said that all the current Bayern players are enjoying their time at the club and that there is no need for extra players to bolster the squad.
"I do not think that we will buy or lose a player in the winter," Rummenigge is quoted as saying by Insidefutbol.com.
"At the moment I am supposing that we will enter the second half of the season with the same team. Everyone is interested in staying at Bayern."
The Bavarian side are currently leading the Bundesliga by four points.
