Clear manipulation by the media. Madrid sites are running full flight with this picture, that is a clear manipulation of what actually happened.
Busquets foot hovered over Pepe's head, and landed on the floor. He never stepped on his head, and I daresay he never even touched any part of his head. A photo snapped just at the right millisecond, paints a totally false narrative.
Suffice it to say that if indeed Busquets had planted his spiked foot on Pepe's ugly mug, he would have done a lot of visible damage, yet non was seen. Also, Pepe hardly reacted, and we all know what a master performer he is, he would have surely milked the shit out of something like that.
