Washington Spirit reserve In 2015, Zadrazil helped the
Washington Spirit reserve team win the
2015 W-League championship. While she went undrafted in the
2016 NWSL College Draft, Zadrazil was invited in March 2016 to attend the
Washington Spirit pre-season training camp as an unsigned player. Later in March 2016 she accepted an invitation to join
Portland Thorns FC's training camp.
Turbine Potsdam Zadrazil agreed a two-year contract with German
Frauen-Bundesliga club
Turbine Potsdam in May 2016. In December 2017, she extended her contract with Potsdam until June 30, 2020. In December 2018, Zadrazil won the inaugural Austrian Footballer of the Year award, voted for by a panel of coaches from the Austrian Bundesliga and awarded by Austrian Press Agency
DiePresse. She subsequently won the 2018–19 Salzburger Leonidas Sportwoman of the Year award. Following the departures of some important players during the summer, Zadrazil became Turbine Potsdam captain for the 2019-20 season, a further sign of her already evident leadership qualities.
Bayern Munich In June 2020, Zadrazil signed a three-year contract with fellow German club
Bayern Munich. Sarah successfully adapted to having more defensive midfield responsibilities at Bayern and won the Frauen-Bundesliga title in her very first campaign, starting 17 and featuring in all 22 league games. The Austrian played
UEFA Women's Champions League football for the first time in her career and quickly established herself as a key component of Bayern's ambitious team, becoming vice-captain alongside
Lina Magull within a couple of years at the club. Bayern Women's sporting director
Bianca Rech spoke about Zadrazil after she signed a contract extension in November 2022, saying: "Sarah has shown in the last two years at FC Bayern how important she is for this team. She's the midfield dynamo for us, especially in a defensive role, and that's what sets her apart. She's very important for us in the team." Zadrazil was part of the Bayern side which went a record-breaking 44 matches unbeaten in the Frauen-Bundesliga from December 2021 to October 2024, winning both the
2022-23 and
2023-24 league titles respectively along the way. She then helped Bayern win their first-ever
domestic double in the
2024-25 season. On 23 September 2025, Zadrazil suffered a cruciate ligament tear in her left knee during a league match against
Freiburg, sidelining her for several months. On 16 December 2025, the Austrian agreed a new contract with Bayern until 2027. == International career ==
