Why does everyone think Pirlo needs a rest simply due to his "advanced age"? True he is not the most physical guy but it does not mean he does not have stamina or endurance. I am not disagreeing with the prevailing viewpoint but I am just pointing out we shouldn't automatically assume he gets tired more easily than the younger team members. After all, most endurance races (iron men, tri/deca-thon, 100 miles...etc) are won by folks in late 30s to mid 40s. As long as we don't demand Pirlo sprint/accelerate too much, running at constant speed is not necessarily more taxing on him than on other players. And he does seem to run at constant speed most of the game with few acceleration/outbursts (required to cut into defense or save on defense)
