He seems to be shouting or saying something? Very likely.
But more importantly, did you notice the Adidas jersey he has on? And how it only has TWO stripes instead of the normal three stripes which Adidas have as their trademark?
Yep, Johan Cruyff was the only player rocking this unique jersey in the 1974 world cup. All the other Dutch players had three stripes on theirs. Why? Because Cruyff wanted it so.
Adidas were the official kit supplier to the Dutch National Team. However, Cruyff had an exclusive personal deal with Puma. He was not willing to be seen wearing the trademark of their rival sports manufacturer.
So he insisted on having only two stripes on his jersey during the tournament.
Supreme Player. Supreme Player Power.
