Fifa hands real atletico transfer ban
I think there may be some confusion here!
FIFA (Fédération Internationale de Football Association) did not hand Real Madrid a transfer ban. In fact, it was Atlético Madrid, a different Spanish football club, that was banned from signing new players for two transfer windows by FIFA in 2015 and 2016.
The ban was imposed due to Atlético Madrid's breach of FIFA's regulations regarding the transfer of players under the age of 18. The club was found to have made irregularities in the transfer of several young players, including the signing of Brazilian forward João Félix in 2019.
Real Madrid, on the other hand, has not been subject to a transfer ban by FIFA.
