Every football club the world over seems to have that one opponent they just never seem to be able to get the measure of.
It doesn't always have to be a top team. Sometimes it's better when it is. At least then it's sort of excusable.
Here's a look at the clubs every current Premier League have just hated facing since the modern era began in 1992.
*Data comes from research conducted by Sky Sports
1. AFC Bournemouth
With Bournemouth traditionally a lower league club and currently in their first ever top flight season, the Cherries don't really have much of a history when it comes to facing the sides they now find themselves up against in the Premier League.
But one team they have never beaten in their history is Liverpool. In seven meetings between the pair, the most recent of which ended in a Liverpool win in August, two draws is the best Bournemouth have managed.
Based on statistics alone, the opponent Arsenal most ought to dread facing is Manchester United. The Gunners have lost more times (21) against United than anyone else in the Premier League era and have conceded more goal, too.
In the more traditional definition of a bogey team, it's actually Swansea who cause more trouble. Since the Welsh side were promoted in 2011, they taken seven points from a possible 12 at the Emirates Stadium.
3. Aston Villa
Aston Villa seem to really struggle when it comes to facing both Manchester clubs. Villa's home record against United is widely known for being poor - the 3-1 victory in August 1995, which prompted Alan Hansen to utter the infamous words, 'You can't win anything with kids', remains one of just two times they've beaten the Red Devils at Villa Park in the Premier League.
In away trips to both City and United, Villa have suffered defeat an incredible 78% of the time.
It is perhaps a little ironic given Jose Mourino's personal record against Arsene Wenger, but Chelsea have found things far tougher against Arsenal than they have against any other Premier League team over the last 23 years.
Chelsea have been beaten 18 times by the Gunners during that time and even went a full 10 years without a Premier League win against their city rivals between 1995 and 2005.
5. Crystal Palace
Crystal Palace might fancy themselves as a future bogey side for a lot of Premier League teams. The Eagles have been on a steadily upward trajectory ever since returning to the top flight in 2013, but one team who continually seems to get the better of them is Southampton.
Palace are yet to taste victory over the Saints in 12 previous Premier League meetings and have been beaten home and away by them in each of the last two seasons.
Everton often find it hard going against Liverpool, but that is perhaps to be expected when the red half of Merseyside has been the more dominant for so long. The Toffees' true bogey side in the Premier League appears to be Crystal Palace, though.
The Eagles have won two thirds of the league games they've played at Goodison Park since 1992. Everton haven't lost a higher percentage of games at home to anyone else during that time.
7. Leicester City
When Leicester returned to the Premier League in 2014, their first game was a 2-2 draw against Everton. It was seen a good result in the context of a newly promoted team, but the Foxes have always found wins against the Merseysiders hard to come by.
In 18 Premier League meetings between the clubs, Leicester have won just once.
For Liverpool, away trips to Manchester City (at Maine Road and the Eithad Stadium) and Chelsea have proved rather troublesome over the years.
The Reds have faced City away on 18 occasions, including games prior to the Sheikh Mansour era, and Chelsea on 23 occasions, but have won just 17% of the time. They don't have a worse record against anyone else they've played more than 10 times.
9. Manchester City
Would you be surprised to learn that Manchester City only managed their first ever home Premier League win against Leicester just last season? That fact doesn't quite reflect the context of their meetings these days, but it's true.
Prior to that 2-0 win in March 2015, City had lost every time they'd faced the Foxes at home in the post-1992 era. It's only three times, but a 75% defeat rate is still rather high.
10. Manchester United
People often forget that Chelsea were a thorn in Manchester United's side long before Roman Abramovich arrived in west London in the summer of 2003 and ploughed millions upon millions into the club.
The current Premier League champions have won six times at Old Trafford since 1992. No other away side has won more games or scored more goals at the famous stadium in that time.
11. Newcastle United
When Swansea cruised to a 2-0 win over Newcastle earlier this season, it was pretty much par for the course as far as Premier League games between the two clubs are concerned.
Since the Welsh side were promoted to the top flight in 2011, Newcastle have lost 67% of games against them, home or away. No other side has such a comprehensive winning record against the Magpies.
12. Norwich City
Norwich will have been glad to see Luis Suarez leave English football in 2014. The Uruguayan has been responsible for almost 1% of all the top flight goals they have ever conceded.
But beyond just individual players, Newcastle are the team that has a real hold on the Canaries. Norwich have never won a Premier League game at St James' Park and have just a single point to show for their their six trips there.
Southampton and West Brom played out a 0-0 draw when they met at the Hawthorns earlier this season. But perhaps that shouldn't have been too surprising for Saints fans, with their team often struggling to score against the Baggies.
The two clubs have met on 11 occasions in the Premier League, but Southampton have only averaged 0.45 goals per game in that time. That's just five goals in total.
14. Stoke City
When Stoke host West Ham at the Britannia Stadium, it appears to be a fairly safe bet that the Hammers will score at some point during the game.
Stoke's Premier League existence has been built on a sound defence and an excellent home record. However, the Potters are still yet to keep a clean sheet against West Ham in six meetings at the Britannia.
Sunderland fans could be forgiven for thinking that everyone is their bogey team. The Black Cats have endured a miserable few years, but have specifically struggled when facing Tottenham at White Hart Lane.
Going back to the 1996/97 campaign, the pair have met 14 times in North London in the Premier League era. Sunderland have lost as many as 12 of those games, winning just once.
16. Swansea City
A bogey side for others, Swansea have never done well against Tottenham in the four years they've been in the Premier League. The Welsh side have only played Spurs eight times, but have lost on seven occasions. The only time they haven't been defeated was the first time the clubs met in this current run - December 2011.
The Swans have also consistently failed to beat Everton, losing five from nine. Their last meeting with the Toffees was a 0-0 draw just last weekend.
17. Tottenham Hotspur
Last season's 5-3 Tottenham win over Chelsea was rather spectacular. The thing is, it was at White Hart Lane. Away from home, Spurs have never actually beaten their cross-town neighbours.
Both ever presents of the Premier League era, there have been 23 meetings between the clubs at Stamford Bridge since 1992. Spurs have lost 15 times and drawn the other eight.
Watford don't have a great deal of Premier League history - this is only the club's third season at this level since English football underwent its major face lift in 1992. In that time, Everton have proved more troublesome for the Hornets than everyone else.
Watford have leaked more goals against Everton than any other team - a grand total of 14 in just five meetings.
19. West Bromwich Albion
Until Saido Berahino scored a winner at Old Trafford in 2013, West Brom hadn't beaten Manchester United at all in 35 years. But having broken that long record, their home form against United in the Premier League is still bad. The Baggies are still waiting for their first win after nine years of trying.
They were painfully close to finally breaking the Hawthorns hoodoo in 2014/15, but a late Daley Blind goal ensured the points were shared.
20. West Ham United
West Ham shocked the whole of the Premier League when they convincingly defeated Arsenal on the opening day of the 2015/16 season last month. That was at the Emirates Stadium, but the Hammers' home record against the Gunners isn't actually very good.
West Ham have lost at home more times to Arsenal (11) than anyone else in the division since being promoted in 1993. Perhaps moving from Upton Park to the Olympic Stadium this summer might change that ...
