Neymar and his sister have a much tighter bond than most ordinary siblings.
The Brazilian forward is so close with his sister, Rafaella Santos, that he has a permanent reminder of her on his body.
Proving his love for his sister, Neymar proudly showed off a massive tattoo of her face that was inked on his right arm in the summer of 2015.
But their loving relationship is not just one sided, as Rafaella returned the favour by getting a tattoo of her superstar brother’s eyes on her left arm.
As well as demonstrating their close bond on their bodies, the pair outpour their love on social media.
When Neymar was criticised for his form when Barcelona were knocked out of the Champions League, Rafaella posted a sweet sentiment in support of her big bro.
“My heart is yours, my love is yours, my smile is yours, my day, my night, my longing, my best company,” tweeted Rafaella.
While her brother is one of the most famous people on the planet, Rafaella has become famous in her own right.
The blogger and model has more than 5.5 million followers on Instagram and often posts snaps with Neymar.
She does a lot of charity work with Instituto Neymar Jr., which was set up by the Brazilian to help disadvantaged children in Praia Grande, Sao Paulo, near to where the siblings grew up.
One of the biggest talking points around the siblings’ relationship is a strange conspiracy revolving around Rafaella’s birthday.
There is a theory over a ‘curse’ of bad luck that struck Neymar around the date of Rafaella’s birth for five years in a row.
Her birthday falls on March 11, and Neymar managed to be in Brazil to celebrate with her despite it being mid-season from 2015 to 2019.
While it seems to be purely coincidental, it hasn’t stopped football fans making jokes and questioning what has gone on.
It all started in 2015 when Neymar was playing for Barcelona as he picked up his fifth yellow card of the season against Granada on February 28.
Because he was suspended for the next match, Barcelona allowed Neymar to fly home to Brazil to be with his family during his sister’s birthday.
The following season an almost identical scenario happened as he was given another suspension during the match with Rayo on March 3.
This time he got permission from then manager Luis Enrique, club captain Andres Iniesta and his three vice-captains – Lionel Messi, Javier Mascherano and Sergio Busquets.
Neymar headed back to his native country for a Disney-themed birthday while he was suspended from playing.
In 2017, Neymar suffered a muscle injury in a match against Deportivo on March 12, so went back to Brazil to celebrate his sister’s birthday once agaon.
The next year he fractured a toe in Paris Saint-Germain’s victory over Marseille on March 3 which ruled him out for the rest of the season.
Neymar was badly injured and faced a race against time to be fit for the Russia World Cup after being sidelined for three months.
He went back to Brazil to undergo surgery on his fractured toe, proving anyone doubting his injury wrong.
Then in January 2019, the Brazilian sprained his ankle during Brazil’s friendly win over Qatar which forced him off the pitch for three months.
The surprising record eventually came to an end this season when Neymar played in PSG’s win over Borussia Dortmund in the Champions League.
The coincidence has not gone unnoticed by fans – and even rival players have made jibes about Neymar always attending his sister’s birthdays.
While discussing the possibility of Neymar making a shock switch to Real Madrid in November 2017, Sergio Ramos couldn’t resist have a dig at his rival.
Ramos spoke about the potential deal, which emerged despite Neymar’s history and strong links with the Spanish club’s bitter rivals, Barcelona.
Admitting the ex-Barcelona star would be welcomed at the Bernabeu, Ramos joked about having to discuss terms with Rafaella.
“I like to play with the best and Neymar is one of them, I hope,” the Spaniard said in an interview with Cadena SER.
He then cheekily added: “What we would have to negotiate is his sister’s birthday.”
Rafaella has often come out against football fans who have been criticising her brother on social media.
Neymar’s sister furiously hit back at PSG fans in an X-rated blast in August last year.
Supporters of PSG branded the Brazilian a “son of a b****” during their season opener against Nimes in Paris.
While fans continuously chanted expletives at Neymar, others displayed their unhappiness with the wantaway star with banners reading Neymar go away.
Neymar had openly admitted that he would like to head back to Barcelona with talks believed to have been held by his representatives.
Rafaella is claimed to have voiced her outrage at the fan’s chants in social media posts which have now been deleted.
In the posts, it is claimed that she said PSG would win nothing without him.
She wrote in English: “WHAT A DISGUSTING AND DISRESPECTFUL HEAPS OF HUMAN Y’ALL ARE! You wish you still had my brother at your team. You will win nada without him. F******”
