All or Nothing: Manchester City (2018, Amazon)

Amazon's all-access documentary following Manchester City's 100-point 2017–18 Premier League season gave football supporters the first genuine inside view of a Pep Guardiola training session — revealing tactical drills, half-time speeches, and the emotional intelligence behind football's most analytically demanding management style. The scene in which Guardiola confronts Fabian Delph about commitment before a key match is the most watched football management footage of the decade. The All or Nothing format has since been replicated by dozens of clubs.
