The Bavarians finished 10 points behind champions Borussia Dortmund last term, but with a new coach in Jupp Heynckes and a new goalkeeper in Manuel Neuer, Schweinsteiger, believes Bayern have to win it back.
"We have a new team, a new coach and want to win titles and play nice football," the Germany international said on www.tz-online.de.
"With this squad we have to win titles."
As the club's longest serving player and with 87 caps for his country, the 26-year-old knows there is more responsibility on his shoulders than most.
"I have been here the longest and know that I have to lead the team," Schweinsteiger added.
