Chelsea face MK Dons in the fourth round of the FA Cup this weekend.
Having defeated League 1 Scunthrope United in their previous outing, it means the Blues face lower-league opposition once more as they attempt to navigate their way to Wembley for the FA Cup final in May.
While that 2-0 victory over Scunthorpe earlier this month proved a positive affair, it's not always been plain sailing for Chelsea whenever they have faced teams outside of the top flight.
There have been some major upsets in recent memory, while if we look back at games that pre-date the Premier League's inception in 1992, Chelsea were on the receiving end of some surprise defeats.
