Transfermarkt

Transfermarkt is a German-based website owned by Axel Springer SE that has footballing information, such as scores, results, statistics, transfer news, and fixtures. According to the IVW, it is in the top 25 most visited German websites, and one of the largest sport websites after kicker.de. The website has scores, results, transfer news, fixtures, and player values. Despite the player values, along with some other facts, being estimates, researchers from the Centre for Economic Performance have found that the "rumours" of player transfers are largely accurate. These estimated player values are usually updated every few months, considering the high inflation and fluctuation of the association football market, these estimates might be slightly lower or higher than what a players' current form and therefore current value might suggest.
