Lahm won eight Bundesliga titles, six DFB-Pokal trophies, and the UEFA Champions League in 2012-13 with Bayern Munich. He also won the UEFA Super Cup and FIFA Club World Cup in 2013, and the DFL-Ligapokal in 2007.
Lahm retired from international football on the 18th of July 2014, after leading Germany to the World Cup. He retired from club football at the end of the 2016-17 season, making his final appearance on the 20th of May 2017 in a 4-1 win over SC Freiburg.
Bayern fined Lahm an estimated 25,000 euros after he gave an unauthorised interview to the Süddeutsche Zeitung in November 2009, in which he criticised the club's transfer policy and its lack of game philosophy and strategic planning.
Guardiola used Lahm as a defensive midfielder from the 2013-14 season, deploying him in a pivot role within a 3-4-3 formation. The role was compared to that of a metodista, a playmaking centre-half in Italian football terminology.
Lahm earned 113 caps for Germany, making him the eighth-most capped player in German football history at the time of his retirement. He scored five international goals across his career.
Guardiola said Lahm was "perhaps the most intelligent player I have ever trained in my career" and that he was "at another level." He made this assessment during Lahm's first season playing under him at Bayern Munich.
