Transfermarkt is a German-based[1] website owned by Axel Springer SE that has footballing information, such as scores, results, statistics, transfer news, and fixtures.

[5] These estimated player values are usually updated every few months, considering how the association football market works,[further explanation needed] these estimates might be slightly lower or higher than what a players' current form and therefore current value might suggest.

The website was founded in May 2000, by Matthias Seidel to track players and transfer targets for SV Werder Bremen before expanding to other teams.

The website initially focused on players, but gradually expanded to include managers, agents, and other staff.

In the course of this update there were both server-technical as well as data-legal issues, as private data was visible to other users for an indefinite period of time.
