Bayern Munich ground out a 3-1 win at Stuttgart and provisionally opened an eight-point lead in the Bundesliga Saturday. The win gave Bayern three more points in its quest to become the first club to win four successive German league titles. "Now we need three more (league) wins and a draw in order to create something that no team in Germany has ever managed," said Guardiola. An own goal from Georg Niedermeier got the defending champion underway in the 31st minute and David Alaba made it 2-0 in the 52nd. Daniel Didavi pulled one back in unorthodox fashion in the 63rd, scooping the ball over the helpless Manuel Neuer while seated after falling in a previous attempt. Bayern substitute Douglas Costa sealed it in the last minute with a shot inside the left post. "We had a lot of problems, we attacked well, but we were a bit too lazy and gave away free-kicks and corners," added Guardiola. "We made life complicated for ourselves, but after taking the lead we improved, espcially in the second half, attacking better and the strikers moved more." Borussia Dortmund can restore the five-point gap Sunday with a win at Schalke. Borussia Moenchengladbach stay fourth despite its 1-0 defeat at Ingolstadt. At the bottom, Hoffenheim, coached by 28-year-old Julian Nagelsmann, the youngest ever coach in Germany's top flight, is now three points clear of the relegation places after its 2-0 win at second from bottom Eintracht Frankfurt. Midfielder Nadiem Amiri, who netted just a minute after coming off the bench, and forward Mark Uth scored its second-half goals. Under Nagelsmann, Hoffenheim has now taken 17 points in its last nine games to climb out of the bottom three to 14th. Augsburg escaped the bottom three, and dropped opponent Werder Bremen into the relegation places, with a 2-1 win in north Germany as South Korea defender Hong Jeong-ho scored its dramatic 87th-minute winner. Mid-table Darmstadt enjoyed a 2-1 win at Hamburg while Friday Hertha Berlin was held to a 2-2 draw at home to bottom side Hanover.
