Real Madrid defender, Sergio Ramos,was reportedly covered by UEFA after he tested positive to drugs in UEFA Champions League final win over Juventus in 2017.
Ramos tested positive for Desametasone after the game, which Los Blancos won 4-1.
Desametasone is a substance that can be used as long as UEFA are notified in time.
The allegations come as part of the latest wave of Football Leaks reports.
Der Spiegel once threaten to reveal a football star who is a “multiple Champions League winner” that tested positive for doping.
A previous issue arose when the Real Madrid players only accepted a surprise doping test in February 2017, if it was performed by club staff rather than the members of the anti-doping team, which is against regulations.
