Alaba's foot injury in pre-season saw Holger Badstuber become a makeshift full-back, with Dante being deployed in central defence.
However, with the 20-year-old nearing a comeback, the Brazilian's place in Jupp Heynckes's side is under threat.
"[Alaba] is a great player," Dante told TZ. "It's amazing how far he has come for his age and he will help the team a lot.
"I'm sure that the coach will also rotate the defence. Who plays is the decision of the coach. Whatever happens, I will continue to work hard."
Dante joined Bayern from Borussia Monchengladbach in the summer.
