Mats Hummels

Bayern Munich: Youth, and 2006–2008

Hummels is a product of Bayern Munich's youth academy, first entering the club as a six-year-old. He signed his first professional contract on 19 December 2006, until 2010. On 19 May 2007, in the season's final match, he played his first Bundesliga match with the first team in a 5–2 home routing of 1. FSV Mainz 05. He also played for the reserve team. In 42 Regionalliga matches Hummels scored five goals for FC Bayern II.

Borussia Dortmund: 2008–2016

In January 2008, Hummels joined Borussia Dortmund, initially on loan. He finished the 2007–08 season with 16 matches played. During his first full season, he quickly established himself as first-choice, as he often partnered newly signed Neven Subotić, but also missed a great part of its final months due to injury. By the end of the 2007–08 season he would lose his first final with Dortmund in a 1–2 loss against his lender club Bayern Munich in the DFB-Pokal final. In February 2009, he was fully signed to the club for a fee of €4 million. In the summer of 2008, he would win his first trophy with Borussia Dortmund in a German supercup match between Dortmund and Bayern Munich, which Dortmund won by 2–1.

The 2010–11 season brought increased success for Hummels. He was the regular first-choice centre-back, again paired with Subotić. The duo helped Dortmund to the best defensive record in the Bundesliga, as the team won the league title. Hummels' performances that season…

Hummels was called by the German under-21 national team for the 2009 UEFA European Under-21 Championship; after getting only minimal playing time during the initial four matches, he started as a defensive midfielder in the final, a 4–0 win against England. He made his senior team debut in a friendly against Malta on 13 May 2010 in Aachen. He came on as a 46th-minute substitute for Serdar Tasci, taking part in a 3–0 win at New Tivoli. Joachim Löw would still not consider him in the final squad for the 2010 FIFA World Cup in South Africa. On 26 May 2012, he scored his first international goal when he headed a free kick from Mesut Özil, albeit in a 5–3 friendly loss away to Switzerland at St. Jakob-Park. Hummels was in the starting line-up for Germany's opening UEFA Euro 2012 match against Portugal and helped them to a 1–0 victory. Hummels went on to play all 450 minutes in Germany's Euro campaign, along with teammates Philipp Lahm, Sami Khedira, Bastian Schweinsteiger, Holger Badstuber, and Manuel Neuer. His team would lose in the semi-final in a 2–1 defeat against Italy.

Hummels scored the second goal in Germany's 4–0 win over Portugal in their first game of the 2014 FIFA World Cup on 16 June, heading a corner from Toni Kroos. After missing the team's round of 16 match due to illness, Hummels returned to the team for the quarter-final against France, where he scored the winning goal in a 1–0 victory at the Estádio do Maracanã, once more heading a free-kick from Toni Kroos.…

Considered one of the greatest German defenders of all time, Hummels was a large, consistent, and physically strong player, known for his powerful tackling and strength in the air, as well as his positional sense, and his ability to read the game and intercept loose balls, which allowed him to compensate for his lack of pace. A technically gifted and tactically versatile centre-back, he was also capable of playing as a sweeper, or even as a defensive midfielder; his composure, elegance, ball playing ability, outside foot passes, and confidence in possession led him to be compared to compatriot Franz Beckenbauer. Hummels was capable of playing either in a back–three or a back–four defensive line-up. Beyond his qualities as a defender, Hummels also stood for his leadership, having captained Borussia Dortmund. He was also known for his goal-scoring ability, scoring in 16 consecutive Bundesliga seasons, setting a Bundesliga record which only Olaf Thon, Michael Zorc, Holger Fach, Bernd Nickel and Willi Neuberger reached before. Despite his abilities, however, he struggled with injuries throughout his career, missing over 100 matches.

Hummels was born on 16 December 1988 in Bergisch Gladbach, North Rhine-Westphalia. His father, Hermann Hummels, was a professional footballer and manager. His mother, Ulla Holthoff, was a professional water polo player. His father worked as youth coordinator at Bayern Munich until he was replaced by Stephan Beckenbauer, the son of Franz Beckenbauer, on 30 March 2012. In a 2012 interview, Hummels noted that his parents and grandparents all hail from the Ruhr region of western Germany. His younger brother Jonas retired at age 25 in 2016, through injuries. His ex-wife, Cathy Fischer, was named as Germany's WAG of the year for 2013. Fischer and Hummels married in June 2015. The couple have a son, born in 2018. Their divorce was finalised in December 2022. Since the end of 2023, Hummels has been in a relationship with German model Nicola Cavanis. In August 2017, he joined the Common Goal Project (an initiative of Juan Mata), being the second footballer to donate 1% of his salary to a collective fund that will support football organizations as a tool to generate sustainable social development throughout the world. In August 2026, Hummels became an investor and shareholder in the German investment group that acquired 90% of Portuguese club Estrela da Amadora for €40 million, alongside Thomas Müller, Yann Sommer and Lucas Hernandez.
