Bayern Munich chief executive Karl-Heinz Rummenigge expects winger Arjen Robben to re-sign with the Bundesliga champions.
Robben, 32, is yet to extend his deal with the club despite his contract expiring at the end of the season.
But Rummenigge said: "I think everything will be clear in January.
"We are very optimistic. Both sides want it. These are good pre-conditions."
The Netherlands international has scored five goals in 10 league games this season and started Wednesday's 3-0 win over RB Leipzig.
Robben has been at Bayern since 2009 after joining from Real Madrid.
