John Stones, playing as the right centre half for Manchester City against Leeds on Saturday, did not make a single tackle and was part of the losing side against a team who were only promoted last year.
Although neither goal was directly his fault, he could not prevent midfielder Stuart Dallas scoring twice and the team's defending did not do much to persuade boss Pep Guardiola he can rest the talismanic Ruben Dias with impunity.
But the match - although unlikely to dent City's relentless march to another title or to save the now top-half Leeds from relegation - also represented the apogee of Guardiola's evolution and redefinition of what a defender, like Stones, should do.
