There have been some sensational family dynasties in football over the years.
The Charlton brothers took England to their only ever World Cup win, the Neville siblings won that famous Manchester United treble and the Toure duo helped City win their first Premier League title.
Some connections through marriage are also well known, with Sergio Aguero formerly being Diego Maradona's son-in-law.
And obviously everyone knows that Harry Redknapp, who is Sky Sports pundit Jamie's dad, managed his own nephew Frank Lampard at West Ham.
But there are some unbelievable relations that not many people have any idea about.
Liverpool midfielder Gini Wijnaldum has a half-brother playing in the Championship, while a newly promoted Premier League boss decides is his sister's husband gets in the team.
Here is a look at some of the most surprising footballers who are actually related:
Mark Viduka and Luka Modric
Possibly the most unexpected family members on the list are Leeds legend Mark Viduka and Ballon d'Or winner Luka Modoric.
Viduka captained the Australian national team, taking them to new heights in the 2006 World Cup, but he could also have played for Croatia.
The former Middlesbrough striker is half-Croatian on his dad's side - with the elder Viduka emigrating to Australia in the 1960s.
Viduka is cousins with Croatian superstar Modric, who became one of the best players in the world.
The blood relatives have actually both played for the same club, but not at the same time, with Viduka playing for Dinamo Zagreb before joining Celtic.
It's the same club where Real Madrid maestro Modric started out his illustrious career.
Viduka now actually lives in Zagreb with his wife Ivana and their kids - and even owns a coffee shop there.
Jay-Jay Okocha and Alex Iwobi
Nigerian forward Okocha lit up the Premier League when he joined Bolton in 2002.
Quickly becoming a fan favourite, the club printed shirts which read "Jay-Jay – so good they named him twice"
After four magical years his time there ended in tense circumstances as he was stripped of his captaincy and left for the Middle East.
Okocha returned to England for Hull's 2007/08 promotion season, but was released by the club and took an early retirement.
However, a member of his family did make it to the dizzying heights of the Premier League once more.
Everton winger Alex Iwobi's mum is Okocha's sister - making the former Arsenal star his nephew.
Having reperesented England at youth level, Iwobi switched to play for Nigeria just like his famous uncle did.
"I can never get tired of people comparing us. I see my uncle as an idol, someone I have always looked up to as a footballer," Iwobi told BBC Sport last year.
"When people compare me to him... it's like 'wow' maybe they see me on his level but I don't believe I am there yet.
"It is what it is, he's a skilful player, I'm quite skilful myself so they are always going to compare me to him especially that he's my uncle.
"I still have a long way to go, maybe one day I can be on his level or greater."
Scott Parker and Harry Arter
West Ham legend Scott Parker has just guided Fulham back to the Premier League via the play-offs.
And he was helped by his wife's brother Harry Arter, who he signed on loan from Bournemouth in August 2019.
Arter has often spoken about his brother-in-law being a positive influence on his life.
When Arter was released by Charlton and struggled to find a new club at the start of his career, Parker let him live in his house and paid him to do jobs.
One year, the pair sat round the table for Christmas dinner, then the following day they faced each other on the football position.
In the strange episode, Arter scored in Bournemouth's 2-0 win over Fulham, who were being captained that day by Parker.
Now working together at Fulham, Arter insists that he is not getting any special treatment from his brother-in-law.
"If no one knew he was my brother-in-law, there’s no way you would have ever thought any different. He treats me no different to any other player," he told The Sun in February.
"It’s made it easy to distance myself from any sort of feeling that Scott is more than just my manager."
He added: "But there have been times when he’s had to leave me out of the team or I’ve come back from suspension or injury and he hasn’t put me back in. It’s as simple as with any other player."
Mario Balotelli and Obafemi Martins
Not much needs to be said about Balotelli, the Italian striker who is always getting in the headlines.
Mario got that famous assist for Aguero for City's last-minute winner against QPR to hand them the title.
But he left for Milan after a reported training ground bust-up with boss Roberto Mancini, returning to England in 2014 for an unsuccessful spell at Liverpool.
You don't want to get on the wrong side of Mario, which is exactly what Obafemi Martins did after joining his family.
Mario was reportedly furious when snaps emerged of Martins hugging and kissing his sister, Abigail Barwuah.
It was claimed Mario disapproved of the relationship, but that didn't stop them getting married and having a baby together in 2013.
Nigerian striker Martins played for Inter Milan for five years but most famously scored the winner in the 2011 Carling Cup final for Birmingham against Arsenal.
Georginio Wijnaldum and Rajiv van la Parra
This is one of the strangest family connections in this list, as they didn't know each other from birth.
Having both grown up in Rotterdam in their native Holland, the half-brothers only met each other for the first time while playing in a youth football game.
“I knew I had another brother, but I never saw him until that moment,” Wijnaldum told The Times.
"I never saw pictures because at that time you didn’t have the internet or social media. There was no Instagram of Facebook or anything.”
"She came to me and told me he was Rajiv. In the beginning I didn’t speak. I was looking at him. But I was also happy because I could finally see him. I went to play a game, but I found my brother."
They both had youth careers at Feyenoord before going their separate ways, but were reunited back in England.
Gini moved from Newcastle to Liverpool in 2016 and has got his hands on a Premier League title and the Champions League trophy.
Winger Van La Parra joined Wolves in 2014, went on loan to Brighton and Huddersfield, then joined the latter permanently.
He is now a free agent after leaving Red Star Belgrade - and wanted by some Premier League clubs.
Gini Wijnaldum and Royston Drenthe
Gini is covering a lot of ground on this list.
The Dutch midfielder is also the cousin of former Everton man Royston Drenthe.
They both have Surinamese roots but were born in Rotterdam in the Netherlands.
The Dutch internationals both ended up in Merseyside but had varying degrees of succes.
Wijnaldum has become a Liverpool hero, but Drenthe had a falling out with David Moyes during his loan spell with the toffees.
Drenthe played at a numver of clubs afterwards including Reading and Sheffield Wednesday.
Philippe Coutinho and Juninho
Two of Brazil's most accomplished players are actually distant cousins.
Juninho became a cult hero in Middlesbrough when he came over in 1955.
A World Cup 2002 winner with Brazil, the attacking midfielder was given the affectionate nickname TLF, or the 'The Little Fella', because of his 5ft 5in size.
Juninho held the record for most goals scored by a Brazilian player in the Premier League until his record was broken...by his own relative.
Coutinho took the honour after scoring 41 goals during five years at Liverpool.
The tricky playmaker was a Reds favourite before he pushed for a big money move to Barcelona in 2018.
But it's not gone very well for Coutinho, who struggled to find his feet and went out on loan to Bayern Munich last season.
Juninho came to our shores in the mid-90s to much furore - and had Middlesbrough fans dreaming of an unlikely success.
It also probably hasn't helped that Liverpool won the Champions League and Premier League after he left Merseyside.
Leroy Fer and Patrick van Aanholt
Fer and van Aanholt are both Dutch internationals, but their parents come from the same small island in the Caribbean.
The cousins both played in the Netherlands under-16s side and worked their way up through the ranks to the first team together.
Van Aanholt joined Chelsea's youth ranks in 2007 and made his professional debut on loan at Coventry in 2009.
The left back enjoyed loan spells at Leicester and Wigan but really came to prominence as Sunderland's star player, earning a well-deserved move to Crystal Place in January 2017.
His cousin started at Feyenoord and played for five other clubs before returning last season.
He joined the Premier League in 2013 with a move to Norwich then switched to QPR before heading to Swansea.
The cousins actually played against each other in 2014, with Fer admitting he was very excited for the clash beforehand.
Fer's QPR faced off against van Aaanholt's Sunderland - with the London-based team coming out 1-0 winners.
Yannick Bolasie and the Lua Lua brothers
Everton cast out Yannick Bolasie was born in France but his parents hail from the Democratic Republic of Congo.
Only 17 players from DR Congo have graced the Premier League - and amazingly three of them are actually related.
The former Crystal Palace man, who was on loan at Sporting CP last season, is the cousin of the famous Lua Lua brothers.
Older brother Lomana moved to England at a young age and has played for a host of clubs, including Colchester United, Newcastle United, Portsmouth and Blackpool.
Lomana has also represented Dr Congo and played for teams in Greece, Cyprus, Turkey and Qatar during a journeyman career.
Meanwhile Kazenga, who is a decade younger than his sibling, started at Newcastle then made his name during a seven-year spell at Brighton.
The winger barely played during half a season at Sunderland and now plays for Luton Town, having played a big hand in helping them avoid the drop last season.
Lionel Messi and Bojan Krkic
Bojan was once tipped to be the next Messi, which makes it even stranger that the pair are distant cousins.
One would go on to become the greatest player that ever graced a football pitch, while the other would flop on cold Tuesday night's at Stoke City.
Argentinian superstar Messi has Catalonian roots and his great-grandfather was the brother of Bojan's great-grandfather.
It was Messi's mother who emigrated to Argentina, while Bojan's family stayed in Spain.
The pair played in the same Barcelona team after coming up through the B team a few years apart.
