Facial database for studying a face research program

Hi all
I’m studing OpenCV and i made a simple program for face recognizing.
I would ask if exist, for example, a soccer face database for creating a searching face program.

Thanks a lot

lfw would be a good start:

or even soccer:

just curious, what do you do there ?

Thanks for help
I am an amateur programmer and I am studying face detection and machine learning.

Please another little help. I don’t know soccer players, and the Jpg files of the face have only the numeric file name. I don’t understand how to merge the filename with the player name.
Thanks in advance

yea, apologies, the soccer datasets are quite useless,
one has no names, the other only 139 images
