The Maradona of 1986 wasn’t an accident or a product of
anthropological forces. In Italy Maradona had worked relentlessly at
finding the right tempo to play, the best way to weaponise his skills
in a brutal defensive game. Italy taught him to play in high-speed
bursts, to spot the moment of weakness, to ration out his strength and
his capacity to take the blows. Mexico 86 was the reward.
I don't want to bang on but this:

Is good and essentially summarises the Diego doc where he goes off and trains with his own coach to do this.
