Manchester City are at loggerheads with Opta over Pep Guardiola's 200th win in charge of the club.
The statistics giant claim that the weekend's 2-1 victory over West Ham was the game in which the manager reached his double century.
But City argue that it was achieved three weeks ago in the FA Cup fifth-round win over Swansea, disputing Opta's judgement, according to the Athletic.
The difference in judgement stems from the fact that Opta refuse to count victories on penalties to the official tally.
