One row per season, oldest first; click a column heading to sort. ▲ promotion and ▼ relegation appear only where the honours name them, so a season without a mark is not always a season without promotion or relegation. Cup is the national cup of the same season, with the last round reached. League counts the regular season. League, play-offs, cup and supercup adds the play-offs, the national cup and the supercup. All games also counts Europe and smaller tournaments. GP includes games without a known score; Win% only counts games with a result. Europe is that season's European cup with the last round the club reached. Head coach only where known; — means not known.
