( CNN ) -- Thomas Muller 's pre-match remarks could have backfired on him and his Bayern Munich teammates . `` The Bundesliga has already been decided , '' the 24-year-old confidently predicted in an interview with Munich newspaper TZ . `` I do n't think anyone is reckoning that we will lose six of our last remaining 12 matches ... '' Make that six of their last 11 as Bayern Munich walloped Schalke 5-1 at the Allianz Arena on Saturday . For the Bundesliga 's fourth-placed side it was a forgettable end to a miserable week . After being taken to the cleaners by Real Madrid in the Champions League on Wednesday , Pep Guardiola 's side found Schalke 's defense in equally accommodating mood come the weekend . David Alaba scored from a free kick in the third minute with Arjen Robben doubling the lead after a quarter of an hour . Mario Mandzukic headed in a third in the 24th minute before Robben 's second four minutes later ended any hopes of a Schalke fightback . Four nil had been the scoreline in the corresponding fixture earlier in the season , but Bayern were n't quite finished . Brazilian right-back Rafinha scored an own goal in the 64th minute to gift the visitors a goal , but 12 minutes later Schalke 's center back Kyriakos Papadopoulos was shown a straight red for bringing down Mandzukic in the penalty area . Up stepped Robben to claim a hat-trick and round off a depressing week for Schalke manager Jens Keller . With Bayer Leverkusen losing 1-0 at home to Mainz , Bayern extended their lead to 20 points and could be crowned champions by the end of March . Elsewhere , Borussia Dortmund backed up an impressive 4-2 win at Zenit St Petersburg in the Champions League on Tuesday with an 3-0 win against Nurnberg . Second-half goals from Mats Hummels , Robert Lewandowski and Henrik Mkhitaryan move Jurgen Klopp 's side up to second with 45 points . In the other matches played Saturday , Werder Bremen beat Hamburg 1-0 while the matches between Augsburg and Hannover and Braunschweig and Monchengladbach both ended in 1-1 draws . Chelsea extend title lead as Arsenal stumble . After registering the only goal and point for English clubs in the last 16 of the Champions League in midweek , Chelsea returned to English Premier League action on Saturday facing west London rivals Fulham . Fulham boss Felix Magath 's task of avoiding relegation got a little bit harder after Jose Mourinho 's side enjoyed a comfortable 3-1 win at Craven Cottage . A second-half hat-trick by Geman international Andre Schurrle earned Chelsea all three points -- John Heitinga scoring a consolation for the home side -- and a four-point lead at the top of the table . Arsenal would have expected to maintain the one-point deficit with Chelsea as they traveled to Stoke but instead slumped to defeat . A 76th minute penalty by Jonathan Walters ensured Mark Hughes ' side scored only a second win in ten matches to boost their survival chances -- victory lifts them to 12th place with 30 points . Whereas Arsene Wenger 's side appear to be stalling in the title race , Liverpool continue to score goals for fun and keep their supporters wondering if they can claim their first league title in 24 years . The foundations for an emphatic 3-0 win against Southampton were laid by a Luis Suarez -- the Uruguayan tucking away his first goal in six games in the 16th minute . Raheem Sterling adding a second in the 58th minute before Steven Gerrard 's injury time penalty made sure of three points . Brendan Rodgers 's team now rise to second ahead of Arsenal on goal difference . Merseyside rivals Everton bounced back from back-to-back defeats with a 1-0 win against West Ham United at Goodison Park while Newcastle United 's mini-revival continued with a 4-1 win against Hull City at the KC Stadium . But the victory was overshadowed when Newcastle boss Alan Pardew was sent to the stands by the referee after clashing with Hull City 's David Meyler . Pardew appeared to head-butt Meyler after the midfielder had brushed past him to retrieve the ball for a throw-in in the 72nd minute . The English Football Association says it will investigate the incident . Manchester City will take Sunderland in the League Cup final at Wembley on Sunday while three league fixtures will also be played with Aston Villa taking on Norwich , Swansea entertaining Crystal Palace and Cardiff traveling to Tottenham Hotspur .
