10. Chelsea 1-1 Burnley (Burnley win on pens) 4th Round 2008
The Championship side managed to knock out the Premier League leaders very early on in the competition back in 2008, after taking the Blues to penalties. At the beginning of the game, it seemed as if Chelsea would wrap up a win, with Drogba putting the Stamford Bridge side in the lead. But a superb performance from Burnley helped turn it around, with Ade Akinbiyi equalising to take the game beyond 90 minutes. After holding out for another 30 minutes, Brian Jensen saved the vital spot-kick to send the Clarets sailing through to the fifth round.
