Currently there have been 8 managers from countries other than Poland, the first being Václav Křížek (Czech Republic) in 1949, and most recently David Badía (Spain) in 2023.
In two of the managerial appointments, the clubs official sources claim there have been two people working together as the manager of the team.
The first such instance was when Lechia-Polonia was first merged with Witold Kulik and Stanisław Stachura managing together for 29 games.
The other instance happened after the sacking of Jerzy Jastrzębowski when Wiesław Wika and Lech Kulwicki jointly became the caretaker-managers.
The dates have been added to try and give the most accurate representation of when the manager held their role at the club.
Some managers are known to have started their role after the winter break, if the official date is not known these will be listed as 1 February as often friendlies/official games were not played in January.
