With the FA Cup Third Round in full swing the smaller teams remaining in the competition will be looking to these games for inspiration to cause giant killings (just like Nottingham Forest did to Arsenal on Sunday afternoon) in the hope of fame, fortune and most importantly progression in the world's oldest cup competition.
Here's a look at nine of the biggest 'cupsets' since 2010:
9. Manchester United 0-1 Leeds United (2010)
Leeds travelled to Old Trafford as a team that had only gone downhill since their last meeting with the Red Devils in 2004. Two relegations left the Yorkshire club in League One and miles away from their old rivals from down the M62.
Everyone expected Sir Alex's team to prevail but Jermaine Beckford's 19th Minute goal sent the away end into raptures and is still lauded by fans as a highlight in a tricky period for the Whites.
8. Stevenage 3-1 Newcastle United (2011)
When this match was drawn everybody thought back to 1998. Stevenage, then a non-league team, held Newcastle to a replay despite the Magpies wanting to swap the original tie to St James' Park. Newcastle ended up winning the replay due to a controversial Alan Shearer goal.
13 years later and Stevenage gained revenge with a brilliant 3-1 win over the Premier League side. A Mike Williamson own goal and strikes from Michael Bostwick and Peter Winn gave the League Two side the victory.
7. Norwich City 0-1 Luton Town (2013)
Luton Town stunned a Norwich City side that featured Harry Kane at Carrow Road in 2013. The then Conference side scored through Scott Rendell with ten minutes remaining to win the fourth round tie.
Luton broke the trend for non-league sides as they were the first since 1989 to beat a top division team and the first since the 40's to do so past the third round.
6. Wigan Athletic 1-0 Manchester City (2013)
2013 saw one of the biggest cup final shocks in recent memory. Big spenders Manchester City were looking to win a second FA Cup in three years when they faced Wigan Athletic in 2013.
However after a Pablo Zabaleta red card, Wigan won the game with a Ben Watson header late on.
5. Warrington Town 1-0 Exeter City (2014)
Warrington Town of the eighth tier knocked out League Two Exeter City in 2014. A seventh minute goal from local plasterer Craig Robinson was enough for Warrington to remain the lowest ranked team in the competition.
It was quiet a result of a club that had never made it out of the qualifying stages in its history.
4. Hartlepool United 1-2 Blyth Spartans (2014)
Seventh tier Blyth Spartans travelled 40 miles for a Second Round tie with League Two Hartlepool United.
A superb free kick from Stephen Turnbull and a 90th minute goal from Jarrett Rivers - who worked in his mother's newsagent during the week - sent the 1,111 Blyth supporters wild.
3. Chelsea 2-4 Bradford City (2015)
Not many teams come from 2-0 down to beat Chelsea at Stamford Bridge, but that's exactly what Bradford City did in 2015.
Goals from Gary Cahill and Ramires gave the Premier League side the advantage. However Bradford fought back with goals from John Stead, Filipe Morais, Andy Halliday and Mark Yeates sent the Yorkshire side through to round five.
2. Sutton United 1-0 Leeds United (2017)
National League Sutton United knocked out Championship side Leeds United in round four last season. A Jamie Collins penalty after an hour was enough for the non-league side. The afternoon got worse for Leeds as Liam Cooper was sent off with eight minutes to go.
1. Burnley 0-1 Lincoln City (2017)
Arguably the biggest shock in recent FA Cup history occurred in the fifth round of last year's competition. National League leaders Lincoln City travelled to Turf Moor and Sean Raggett's 89th minute header sealed the tie for the Imps and sent the away supporters into pure ecstasy.
