On 13 December, after his good run of form in the first half of the Bundesliga season, Müller pledged his allegiance claiming he was at home in Munich and that, "There is no club to step up from when you leave FC Bayern... there almost is no better club." Six days later, he signed a two-year contract extension, keeping him at the Allianz Arena until 2017. At the winter break in the Bundesliga, he had nine goals and seven assists in 16 league appearances and a further three goals in the Champions League; this gave him a total of 13 goals halfway through the season, including his strike against Borussia Dortmund in Bayern's win in the 2012 DFL-Supercup. Müller scored his first goal in Bayern's second game back from the break in a 2–0 away win over VfB Stuttgart. Müller tapped in his fifth goal of the Champions League campaign on 2 April, completing a 2–0 first leg defeat of Juventus in the quarter-finals, ending the Italian club's 18-match unbeaten record in Europe.
