The F.A Cup third round draw has been made, and supporters up and down the country have mixed feelings after being presented with their ties.
It's the competition that lets non-league teams dream, gives top-half Premier League teams the chance to add another trophy to their cabinet, and allows Championship teams to build some momentum as we approach the business end of the campaign.
There are some teams that will be looking to rotate their squad to ease through into the fourth round, whilst some supporters will already be planning a day trip out, in the hope of their team pulling off a famous cup-upset.
It has been a disappointing draw for some - Aston Villa host promotion rivals Swansea City, whilst Leeds United travel to Championship counterparts Queens Park Rangers.
The likes of Nottingham Forest and Reading fans will be absolutely delighted with their cup-draw though, with a trip to Premier League giants Chelsea and Manchester United on the horizon, respectively.
Here, however, focusing on League One, we take a look at those sides that will be confident of causing an upset following the F.A Cup draw...
League One table-toppers Portsmouth have been drawn away to Championship table-toppers Norwich City.
The Blues have lost just one game in the league thus far this campaign, as Kenny Jackett's sit four points clear of second-place Sunderland in the Sky Bet League One standings.
It's bound to be a tough test for Pompey, with the Canaries sitting at the top of the league having won seven of their last eight games - but if anyone is capable of pulling off a shock, it's the 2008 winners.
Nathan Jones' Luton side have been drawn away to Championship strugglers Sheffield Wednesday.
The Hatters have shot up the League One table following promotion from League Two last term, and sit third in League One having won six of their previous seven league outings.
Wednesday, on the other hand, are struggling towards the foot of the Championship table - Jos Luhukay has come under major criticism with the Owls languishing in 16th position having won just one of their last eight league games.
The Hatters are likely to be backed by a healthy travelling contingent having took over 6,000 fans all the way to Newcastle United last term, and I definitely wouldn't put it past Nathan Jones' men pulling off an upset.
Finally, Daniel Stendel's Barnsley have been given an away draw at Premier League side Burnley.
The Tykes have excelled under Stendel this term, and the Yorkshire club sit 5th in Sky Bet League One after 10 wins from 19 games this term.
Burnley have been in dismal form in the top flight this term - Sean Dyche's men sit 19th in the Premier League after winning just two games all season.
The latter is likely to rest key players in preparation for their climb up the Premier League table, so there is no reason whatsoever why Barnsley cannot pull off an upset.
