If you ever needed proof that soccer runs in the family, this is it. As a result, fans have occasionally been treated to players who share more than just an ordinary bond as team-mates.
Nothing beats a bit of fierce sibling competition, and we can only imagine how much the rivalry is amplified when you're trying to avoid being the less talented brother in front of an audience of millions.
However, brotherly bickering and family feuds had to take a back seat when these seven related duos shared the field.
Gary and Phil Neville
Perhaps the most well-known brothers in soccer are the Nevilles, who grew up together playing for Manchester United.
Whether it was just their preferred position or a genius tactic to keep them away from each other, Gary and Phil plied their trades as opposite full-backs, with Gary best known for cementing his place on United's right flank.
The pair went on to make a combined 663 appearances for the Red Devils during their time in Manchester and won six Premier League titles alongside each other.
After developing side by side in the academy, the Neville brothers formed part of the famed class of '92, consisting of Manchester United's homegrown talents that went on to dominate domestically.
However, while both go down as club legends, it was Gary that went on to enjoy the better career overall - sorry Phil - after nailing down his role as a starter in Sir Alex Ferguson's side, and enjoying a 19-year career at Old Trafford.
In comparison, Phil was often used to plug holes in the side and never enjoyed a consistent run of games in the iconic red jersey. He eventually left to join Everton in 2005 and retired eight years later.
Thiago and Rafinha Alcantara
As the older brother, Thiago was first to make his breakthrough, featuring for the Catalan club in 2009, two years before Rafinha then joined him.
Despite sharing a dressing room, both members of the Alcantara family never truly found their feet in Barcelona, and enjoyed more success apart in separate clubs.
Fabio and Rafael
Another Manchester United duo that entertained the Old Trafford faithful are Brazilian brothers, Fabio and Rafael.
Gifted with an equal amount of talent and tenacity, the pair quickly became fan favourites at the Theatre of Dreams, often displaying a fierce passion for the badge.
Similarly to the Neville's, both Fabio and Rafael played as opposite full-backs, although it was Rafael who enjoyed the better career in Manchester, making over 100 appearances for the Red Devils compared to Fabio's 22.
The twins also represented their national side in 2011 and 2012 respectively, but only managed two appearances each, and never had the pleasure of sharing the pitch.
Kolo and Yaya Toure
From the red half of Manchester to the blue, the Toure brothers not only played for some of the best teams worldwide but are also central to one of the greatest chants.
With shouts of "Kolo" and "Yaya" still echoing around the Etihad Stadium to this day, it's fair to say that the City faithful hold the duo in high regard after their time at the club.
Kolo was the first to move to Manchester, joining the Sky Blues in 2009 after a seven-year stint in north London with Arsenal.
Yaya joined his brother just a year later, after completing a £24million move from Barcelona.
The pair would only spend three years together in Manchester, but crucially formed part of the side that won Manchester City their first-ever Premier League title in 2011/12.
Younger brother Yaya actually enjoyed his most successful season in Manchester the year Kolo departed, scoring 20 goals from midfield in 2013/14 as City collected another league title.
The duo faced one another in March 2015 after Kolo made an appearance from the bench for Liverpool in a league clash against Yaya's Manchester City.
However, Phillipe Coutinho's winning goal in the 75th minute meant that it was Kolo who had the bragging rights from their first game against each other - we bet the family dinners were fun after that.
Thorgan, Eden and Kylian Hazard
We need to find out what is in the water in the Hazard household. Not only do all three brothers play professionally, but also their mother and father both played too.
It's one hell of a five-a-side team, but big brother Eden would certainly wear the captain's armband. The 30-year-old forged a wonderful career during his time at Chelsea and completed a staggering £100million move to Real Madrid back in 2019.
However, since joining the Galacticos, Eden's career has somewhat stalled, and it's little brother Thorgan who has stolen his limelight after standing out for Borussia Dortmund in recent years.
Thorgan moved to Chelsea in 2012 - the same year as Eden - but struggled to have anywhere near the same impact as his older brother, failing to make an appearance in the first team.
But the 28-year-old has since found his feet at Dortmund and has also found his way into the Belgium side, where he plays alongside brother Eden, even sometimes taking his starting spot.
Kylian hasn't quite reached the same heights as his brothers, and currently plays for Belgian side Cercle Brugge. But at just 26, he still has a few years yet to maybe make an appearance alongside his siblings.
Frank and Ronald De Boer
They came as a packaged deal, and it was quite the bargain. The twins both started their career at Ajax, with Frank as a central defender and brother Ronald as a tricky attacking midfielder.
The pair both made their breakthrough to the first team in 1988 and went on to win five league titles and a Champions League with their beloved Ajax.
After a fallout over contract negotiations, both brothers moved to Barcelona in 1999 as part of a combined £22million fee and went on to win the 1998/99 La Liga title.
After seeing out their careers in Qatar, Frank has since gone into management but missed a trick by leaving brother Ronald out of becoming an iconic double act on the sidelines.
Jacob and Josh Murphy
Both Murphy twins showed their close relationship on the pitch when playing alongside each other for Norwich City.
They started at Norwich's academy together aged seven and rose through the ranks together before being handed their debuts in 2013.
Playing on opposite wings, the teenage duo together made over 100 appearances for the Canaries before parting ways in 2017.
During their spell at Norwich, both brothers went out on loan to gain experience, but Jacob was the first to make a permanent move in 2017, joining Newcastle United where he continues to play now.
Following loans at Wigan and MK Dons, Josh also decided to depart Norwich in 2018, moving to Championship side Cardiff City.
The duo are yet to play against each other since their moves away, but at 26, there's plenty of time yet for a competitive family reunion.
