Nottingham Forest have hardly made a habit of knocking over Premier League opponents down the years, but Chelsea could be added to a notable list of scalps.
Securing a return to the top-flight is currently the priority for the Reds, having spent so long in the wilderness.
Not since 1998/99 has the club rubbed shoulders with English football’s elite, with a whole new millennium having been welcomed in since then.
Forest have, however, locked swords with a number of sides from the leading division during their various spells on the outside looking in.
A trip to Stamford Bridge on Saturday is set to offer another timely reminder of the company the Reds could be keeping if a promotion bid can be pieced together, and provide another opportunity to rock the establishment.
Such success has been enjoyed on eight previous occasions, against five different opponents, with the FA Cup third round having proved to be a happy hunting ground of late.
1993/94: West Ham
Forest had more pressing concerns than a League Cup run after slipping out of the top tier, but made their way to the fifth round thanks in part to a 2-1 victory over the Hammers.
Kingsley Black and Stan Collymore were on target for the Reds, who saw a midweek knockout encounter provide the meat in a derby sandwich of league meetings with Leicester and Notts County.
1993/94: Manchester City
Having disposed of West Ham in round two, Forest repeated their Premier League trick by dumping out City at the next stage.
They required a replay to get the job done, having been held to a goalless draw on home soil, but Neil Webb and Colin Cooper found the target at Maine Road to keep the fires burning in what would be a memorable campaign for the club.
Forest were a League One outfit when welcoming the Addicks to Trentside in January 2007, but proved more than a match for a slide slowly slipping out of the top tier.
Junior Agogo turned home a James Perch cross to open the scoring, before Grant Holt nodded in a Nicky Southall centre to send the Reds into the FA Cup fourth round.
2008/09: Manchester City
Big-spending City were not the side they are today when Forest visited Manchester in the FA Cup third round, but the Abu-Dhabi millions had started to wash into the club.
Billy Davies was not officially in charge for this fixture, having been appointed a few days earlier, but the Scot watched on as Nathan Tyson, Rob Earnshaw and Joe Garner sealed an impressive 3-0 win.
2013/14: West Ham
Sam Allardyce named a youthful side for a visit to the City Ground and was made to the pay price as an inspired showing from the Reds piled pressure on the beleaguered Hammers boss.
Jamie Paterson was the star of the show as he bagged a hat-trick, with Djamel Abdoun having broken the deadlock from the penalty spot early on and Andy Reid wrapped up an FA Cup third round rout in stoppage-time.
Jason Cummings has just four Forest goals to his name, and half of that haul was recorded during a League Cup clash at St James’ Park in August 2017.
The Reds fell behind on Tyneside, but hit back with two first-half goals before Des’ boy, Tyler Walker, snatched an extra-time winner to condemn the Magpies to their earliest exit from the competition in 27 years.
Arsene Wenger brought his FA Cup holders to the City Ground looking to stage a successful defence of a prestigious prize, but left with a famous trophy having been ripped from the Gunners’ grasp.
Forest converted two penalties on the day, from Ben Brereton and Kieran Dowell, but it was Eric Lichaj’s brace (including a stunning volley which famously landed him a dog!) which stole the headlines.
Aitor Karanka’s current charges have already seen off one Premier League side this season, with the Magpies getting sick of the sight of the Reds in League Cup action.
Twelve months on from sending them packing at the second round stage in 2017, Forest repeated the trick on home soil this term courtesy of two stoppage-time efforts from Matty Cash and Gil Dias in a dramatic 3-1 win.
