BERLIN, Feb. 9 (Xinhua) -- Front-runner Bayern Munich humiliated helpless Schalke 4-0 to extend their gap atop the standings to 15 points as Hamburg trashed Dortmund 4-1 in a high paced encounter at the 21st round of Bundesliga on Saturday.
Bayern Munich benefited on Dortmund' s surprising 4-1 slip to Hamburg to establish a 15 point gap. The "Bavarians" dominated the "Royal Blues" in every department from the kick off. Bayern' s Mario Gomez, Franck Ribery and Arjen Robben approached Schalke's goal dangerously by then goalkeeper Timo Hildebrandt disarmed all efforts with his saves.
With 19 minutes into the match Bayern opened the scoring through David Alaba who converted a penalty following a foul play by Marco Hoeger who brought down Ribery inside the box.
Bayern dictated the proceeding on the pitch as Bastian Schweinsteiger doubled the lead with a dead ball goal, when he curled the ball over the wall into the near left post with 32 minutes on the clock.
Schalke was incapable to keep up with the German record champion thus Alaba sealed his brace after an assist by Gomez six minutes into second half.
Bayern were not done with the scoring as Gomez made it 4-0 at the 63rd minute to seal the deal ahead of time against helpless Schalke.
Bayern tighten their position on first position with 54 points meanwhile Schalke drop from 6th to 9th position with 29 points.
Hamburg surprisingly crushed Dortmund 4-1 to inflict them the fourth loss of the season. The "Rothosen" started highly motivated into the match whereas Dortmund needed some time to gain a foothold into the match.
Still it were Dortmund that had the chance to break the deadlock through youngster Mario Goetze who shot just wide of the far post from inside the box, with 15 minutes played. His teammate Robert Lewandowski staged a better figure two minutes later, when he capitalized on a black out by Hamburg' s Heiko Westermann, to slot home the opener on home soil.
Hamburg answered a minute later when a combination by Marcell Jansen via Dennis Aogo found Artjoms Rudnevs inside the box, who tapped in from close range.
With 26 minutes into the match Hamburg grabbed the lead through Heung Min Son following a solo run and goal. The South Korean shrugged off defender Mats Hummels to curl home into the top far post corner.
Dortmund' s situation worsened at the 31st minute as Polish international Lewandowski was sent off with a straight red card following a rude foul to Per Ciljan Skjelbred.
The hosts levelled the score just before the break but Mario Goetze's goal was denied due to an offside position by Marco Reus.
Hamburg' s Jeffrey Bruma weakened his side at the 59th minute following a professional foul to Reus to book a red card.
Nevertheless, the visitors remained unfazed as Rudnevs made it 3-1 on the scoreboard to seal his brace, after he nodded home a cross by Rafael van der Vaart at the 62nd minute.
The hosts kept it bowling but all their efforts remained unrewarded as Hamburg' s Heung Min Son tapped in an assist by Marcell Jansen to mark the final 4-1 score.
Hamburg jump from 9th to 5th position with 31 points whilst Dortmund stay on 2nd position with 39 points.
Leverkusen failed to take over second position as they shared points with Monchengladbach after a 3-3 draw in a see-saw match.
Efficient Monchengladbach grabbed the lead twice thanks to the goals by Martin Stranzel and Luuk de Jong but yet wasteful Leverkusen came back through Sidney Sam and Stefan Kieling. The "Werkself" grabbed the lead for the first time in the 64th minute owing to the goal by Andre Schuerrle until Patrick Herrmann ensured parity in the dying minute of the game.
Both sides remain on their positions, Leverkusen on 3rd with 38 points and Monchengladbach on 7th with 30 points.
Bremen ensured their second win in row when they swept 4-1 over struggling Stuttgart that suffered their fifth straight loss. Bremen stays on 11th position with 28 points whereas Stuttgart slump to 14th position with 25 points.
Elsewhere, Hoffenheim lost 1-0 to Hannover, Wolfsburg defeated bottom team Greuther Fuerth 1-0 and Frankfurt were held to a goalless draw with Nuremberg.
