Gomez, who has already struck four times in the league, will give Bayern a big lift but winger Robben looks unlikely to have overcome his groin injury in time for their defence of the top spot against offensive Freiburg.
"The break [because of international matches] did Robben a lot of good. But whether that is enough for him to play on Saturday still remains to be seen," said Bayern Sports Director Christian Nerlinger. Robben only resumed training a few days ago.
"We have a block of games in front of us which will challenge us but could also see us lay the foundations for a successful season," Nerlinger said.
"These are the weeks for which we love playing football," said captain Philipp Lahm. "We are on a good run but we have not yet reached the point where we want to be."
Freiburg will not be looking to build "park the bus" against Bayern. In three of five games in all competitions coach Marcus Sorg has boldly fielded more than one striker.
"We need to maintain the courage we have shown against them in previous games," said Freiburg forward Stefan Reisinger.
"Maybe that way we will have a chance instead of waiting to see what they will do and wait for a quick break."
