SCORES LEVEL AT 3-3 STORY: Leaders Bayern Munich demolished Schalke 04 4-0 with two goals from Austria international David Alaba to keep their title charge on track and open a 15-point gap at the top of the Bundesliga on Saturday. Left back Alaba scored either side of a sensational Bastian Schweinsteiger free kick with Mario Gomez, starting ahead of top scorer Mario Mandzukic, drilling in the fourth as Bayern made it four straight wins this year without conceding a goal. In another impressive display of fluid, attacking football, Bayern outplayed Schalke, launching an avalanche of pressure from the start and missing several other clear chances as they chase their first title after two failed campaigns. Bayern move on to 54 points with their 17th win in 21 league games while fellow Champions League competitors Schalke, badly missing a string of injured players and having notched only one win in their last 10 games, dropped to ninth. Second-placed champions Borussia Dortmund suffered a surprise 4-1 drubbing at the hands of visiting Hamburg SV to remain on 39 points while Bayer Leverkusen conceded a late goal to draw 3-3 with Borussia Moenchengladbach and stay third on 38. Dortmund took an early lead when Robert Lewandoski took advantage of a mistake at the back by Hamburg, but the vistors hit back to take the lead with goals from Artmos Rudnevs and Son Heung Min. Lewandoski turned villain when he was sent off for a rash challenge on Per Skjelbred during the first half, and although Hamburg's Jeffrey Bruma saw red 30 minutes later, it didn't stop his team extending their advantage through second half strikes from Rudnevs and Heung-Min. In a thrilling battle in Moenchengladbach, the hosts twice led only to be pegged back by Leverkusen. Andre Schurrle then gave the visitors the lead, but Patrick Herrmann rescued a point with five minutes to go.
