Club

As a teenager, Katarzyna Kiedrzynek played handball and football, as a striker at first, then a goalkeeper. After the two sports could no longer be reconciled in terms of time, she decided to play football. From 2010 to the summer of 2013, she appeared for Górnik Łęczna in the Polish Ekstraliga.^[3] During this time Kiedrzynek also became a national team player. For the 2013/14 season she moved to the French first division club Paris Saint-Germain. Her coach Farid Benstiti had already become aware of her during his time as the Russian national coach during an international match against Poland.^[4]  Her debut in the Ligaelf took place at the beginning of the second half of the season in December 2013 with a 9–0 win at bottom AS Muret.^[5] With Paris she finished in 2014 – at that time in the hierarchy of goalkeepers only in third place –  and 2015 behind Olympique Lyon in second place in Division 1 Féminine.^[6] In May 2014 she was in the starting line-up for the French Cup final. She became the undisputed number one goalkeeper at PSG in her second season after beating Karima Benameur and the newly signed Ann-Katrin Berger. In the 2014/15 season, Kiedrzynek played in all nine Champions League games for the Parisians.^[7]

Benstiti saw her qualities above all in the fact that she is willing to constantly work on herself, and also praises her "air superiority" in the penalty area and her handling of the ball with her feet.  Kiedrzynek remained the first choice even under Benstiti's successors Patrice Lair and Olivier Echouafni, although she had a strong new competitor, Christiane Endler, since 2017. In the 2019/20 season, the coach mostly gave preference to Endler in league games. In the summer of 2020, Kiedrzynek therefore joined VfL Wolfsburg, with a contract of three years.^[8]  At the start of the Bundesliga, she was in goal for Wolfsburg in a 3–0 win against SGS Essen.

National team

Kiedrzynek has been part of the Poland national team since 2011. In 2011 and 2013 she guarded the Polish goal against her "second sporting homeland" France in two friendlies.
