Three Sky Bet League 1 sides have the chance to cause major upsets in the FA Cup with Budweiser fourth round this weekend.
Stevenage - who host Everton - and Sheffield United - who face Fulham - have home advantage against their Barclays Premier League opposition, as the BT Sport cameras come to town.
But fellow League 1 side Coventry City face the most daunting of tasks - a Friday night trip to the Emirates Stadium to take on Arsenal, the current Premier League leaders (kick-off 7:45pm, live on BT Sport 1).
Steven Pressley's side have been going well this season, having started the 2013-14 campaign on -10 points after going into administration.
The Sky Blues have faced the added difficulty of playing their home games in Northampton, having fallen out with their Ricoh Arena landlords.
Coventry's cup run has helped to lift spirits in the East Midlands, after a number of difficult years.
However, they travel to Arsenal as almighty underdogs, with Arsène Wenger's side the overwhelming favourites to qualify for the last 16.
Stevenage too are at long odds to see off Everton in their fourth round tie, which kicks off at 5:30pm on Saturday January 25th.
Graham Westley's side remain rooted to the bottom of the third tier, four points from safety with a goal difference of -20. And with just one win in the last nine outings, they are hardly a side in form.
But the FA Cup can be a great leveller, even when you are playing the Barclays Premier League's sixth-placed team. Everton will look for an early goal to settle any nerves as they make the trip south to Broadhall Way.
Sheffield United may fancy their chances against a Fulham side who have had their own struggles during the 2013-14 campaign.
After a woeful start, the Blades have picked up under new boss Nigel Clough, and are slowly edging away from the League 1 drop zone.
The home side will need vocal support from a packed Bramall Lane, but may fancy their chances after knocking out Aston Villa in the third round earlier this month.
Sheffield United v Fulham is live on BT Sport 1 at 1pm on Sunday January 26th.
