The duo were back in training on Monday to boost a Bayern side who have faltered since the mid-season break, with three games yielding just four points.
Ribery and Rafinha have missed all of those matches, the Frenchman having sustained a thigh injury and the full-back having damaged ankle ligaments.
"We want to move on up. We'll prepare well this week and then hopefully give our fans at the Allianz Arena something to shout about," defender Alaba told the club's official website ahead of the 100th meeting between Bayern and Hamburg.
"It's good to have Franck and Rafa back. We need them as they're both very important players."
Bayern will not need any reminding of the difficulties that Hamburg can pose, with September's Bundesliga meeting ending goalless.
Pep Guardiola's side did have more joy the following month in a DFB-Pokal clash that ended 3-1 to the visitors at the Imtech Arena.
Last term they did it three times, scoring 12 goals in the process - the same number they racked up in just two games the season before.
Hamburg have to go back to 2009 for their last win over Bayern, with their last victory at the Allianz coming two years earlier.
But Josef Zinnbauer might prefer to reflect on more recent history, as his first game at the Hamburg helm was the stalemate against Bayern.
"I think we can cause an upset," he told Sport Bild. "But even a draw would be quite special."
Bayern's lead at the Bundesliga summit is eight points and they have won nine of their 10 home league matches in this campaign, conceding just three goals.
