The Bavarian giants have swept all before them again this season, with the German and European champions 20 points clear of second-placed Borussia Dortmund with 10 games left to play.
Bayern secured their spot in the UEFA Champions League quarter-finals on Tuesday, sealing a 4-1 aggregate win over Arsenal, and host Bayer Leverkusen on Saturday.
Third-placed Leverkusen were the last team to beat Bayern in the Bundesliga, winning 2-1 at the Allianz Arena in October 2012.
But when quizzed on Bayern's unbeaten streak, Alaba told the club's official website: "It's an incredible number but, to be honest, I wasn't really aware of it.
"And it's not an issue in the team. We try to focus on the important thing. Runs like that aren't a priority."
With just two wins in their last 12 matches, Sami Hyypia's men have been knocked out of the Champions League and DFB-Pokal, as well as slipping from second to third in the table.
However, Leverkusen are one of just two clubs - Freiburg the other - to avoid defeat against unbeaten Bayern in this season's Bundesliga, as they claimed a 1-1 home draw in October.
"They've often shown they're a good side," he added.
"We can't afford to think it will be a walk in the park. We need to play to our strengths to win this game."
