They did, so Brazil took full advantage of it. The 1970 team style used a lot of ball control, counterattack and not some frenetic attacking style. Italy had to run a lot after the ball that went from Gerson-Pele-Clodoaldo-Rivelino-Piazza-Tostão, so in the second half they had no chance to follow Jairzinho. And of course, it was hot and in a high city. Carlos Alberto famously said he run after the goal during the celebration because he was afraid to throw up in the field and couldnt even lift his arms.
