Widely regarded as one of the greatest players of his era, Müller has been praised for his positioning, finishing, playmaking, work-rate, and consistency in both scoring and creating goals.

A product of Bayern Munich's youth system, Müller has represented the club ever since. With Bayern, he has won a record thirteen Bundesliga titles, six DFB-Pokals, eight DFL-Supercups, two UEFA Champions League titles, two UEFA Super Cups, and two FIFA Club World Cups. He joined the first team in the 2009–10 season after Louis van Gaal was appointed as the main coach; he played almost every game that season as Bayern won the league and cup double and reached the 2010 UEFA Champions League final. Müller scored in the 2012 UEFA Champions League final though Bayern lost the final on penalties. Müller scored 23 goals in the 2012–13 season as Bayern won a historic treble; the league title, cup and Champions League. He broke the Bundesliga record for assists in a season with 21 (a joint record in the top five leagues alongside Lionel Messi in La Liga) and scored 14 goals in 2019–20 season as Bayern won a second treble. With over 750 matches played across seventeen seasons, Müller is Bayern's all-time record appearance holder marking 248 goals and 281 assists for the club across all competitions, and one of only three players in league history to reach the landmark of 100 Bundesliga goals and 100 assists each (alongside Andreas Möller and Marco Reus).
