Jupp Heynckes' men dominated Arsenal during the first leg at the Emirates Stadium, bringing a 3-1 lead home to Germany.
Although a vast majority expect Bayern Munich to finish off the Gunners during the second leg, Mandzukic told the club's official website that he was wary of an Arsenal comeback.
"A lot of people think we’re already through to the next round, but anything can happen in football," Mandzukic pointed out.
"Provided we play the way we did in London we need have no worries. Nevertheless, if we concede an early goal, it could be dangerous."
Scorer of his team's third goal in London, Mandzukic's strike against the Gunners was also his first in the Champions league. While glad to break his duck, the Croatian international was happier that Bayern came away with the victory.
"I'm obviously delighted about the goal, partly because it was an odd one," Mandzukic said.
"The press were saying I lacked a goal in the Champions League, but I never let it get to me. The only thing that ever matters to me is winning."
