There can be few things more frustrating in football than coming out second best against one particular rival time and time again.
That is a fate that has befallen numerous clubs over the years and the Merseyside derby is one notable example.
Everton are without a win against near neighbours Liverpool in any competition since 2010, with the Reds having won eight of the subsequent 17 clashes - the other nine finished in a draw.
The sides meet at Anfield in the Premier League on Sunday, with Everton looking for a first victory on enemy territory since 1999.
But the Toffees are far from the only club to find themselves in a sticky situation against their rivals.
Here we take a look at some of the more one-sided rivalries of recent times, with the help of Opta data.
UNITED SUFFER CHELSEA BLUES
The all-time record may heavily favour Manchester United, who have won 74 and lost 53 of the 181 meetings in all competitions, but since 2012 Chelsea have had the bragging rights.
It is a rivalry created by the London club's emergence into the top-flight elite, for which Roman Abramovich's arrival in 2003 was the catalyst.
The first Abramovich-era clash saw Chelsea run out 1-0 winners, but it is over the past six years that they have really stamped their authority on clashes between the two.
After a controversial 3-2 loss at Stamford Bridge in October 2012 in which Branislav Ivanovic and Fernando Torres both saw red, Chelsea faced United four more times that season without losing.
In fact, a dose of revenge was served just three days later in a 5-4 League Cup success.
Including that nine-goal thriller, Chelsea have lost just twice in 17 matches against United.
LE CLASSIQUE NOT SO MAGNIFIQUE FOR MARSEILLE
Paris Saint-Germain against Marseille is another fixture where the overall record hides the true nature of this clash these days.
It is a heated derby between arguably the two biggest clubs in France, but – as with Chelsea – PSG's dominance has become particularly apparent since 2012.
PSG's unbeaten streak against their rivals now stretches to 18 matches and they have kept clean sheets in eight of those.
Worse still for Marseille, the last four losses have come at the expense of 13 goals conceded, although a 2-2 draw amid that run did help to restore a modicum of pride.
FEW THINGS MORE CERTAIN THAN A BARCA WIN OVER ESPANYOL
Okay, so it will come as little surprise that Barca have repeatedly got the better of this derby, as the Camp Nou club have a winning record against most teams.
However, the extent of their superiority is quite remarkable, with Espanyol having won an away El Derbi match in the league just once since the 1981-82 season.
That solitary success came in February 2009, when Ivan de la Pena's double against his former club secured a 2-1 win.
It was but a bump in the road for Barca, who went on to win the league, and they have since more than reasserted their authority.
There have been numerous thrashings dished out by the five-time champions of Europe, including a 5-0 LaLiga drubbing in September 2017.
At home, Espanyol have not fared much better, failing to win the last 11 league meetings.
Credit where it is due, though, Espanyol grabbed a 1-1 home draw in the most recent meeting in February and prevailed in a first-leg Copa del Rey clash the month before, albeit they were ultimately beaten in that tie.
PEP CAN'T FATHOM KLOPP'S REDS
Manchester City swept all before them in the Premier League last season, racking up 100 points and 106 goals.
But Jurgen Klopp's Liverpool provided a sterner test than anyone, for the most part.
It must be said that Pep Guardiola did oversee a resounding 5-0 win over the Reds early in the campaign, but the tide turned after that.
Liverpool won the next three clashes, inflicting one of only two top-flight defeats on City and dumping them out of the Champions League.
The recent record has been made no less flattering for Liverpool following October's 0-0 draw at Anfield, with the Merseysiders having lost only twice in the last 11 matches against City, one of those a penalty shoot-out reverse in the 2016 League Cup final.
With a title race firmly underway and these two clubs at the centre of it, the January meeting between them at the Etihad Stadium could be pivotal.
