It's harder than it looks.
An unbeaten season was always the dream of Arsene Wenger who believed it to be the best possible way to show complete dominance. Every season, we ask which teams could possibly achieve the feat - but no one has for a while.
Across Europe, some of the Champions League's regular entrants have recorded undefeated seasons in the last half-century, though. Check out 1986 to 1989 in Romania, where one side managed three of them on the bounce.
It's a niche subject but today, we're asking you which teams have been unbeaten all season long - domestically, at least - since 1970.
