The letter R in our World Cup A to Z is for relatives, as we take a look at a number of family links at the World Cup...
The Chanov brothers
The 1982 World Cup in Spain was a significant tournament for relatives with Soviet Union duo Viktor and Vyacheslav Chanov becoming the first, and only, goalkeeping brothers to appear in the same squad at a World Cup.
Interestingly, though, neither of the brothers played a single minute at the tournament as Rinat Dasayev - widely regarded as one of the greatest Soviet goalkeepers - was first-choice.
The Mexican trio
When Manchester United's Javier Hernandez appeared for Mexico in South Africa for the 2010 tournament he became the third generation of his family to play at a World Cup.
His father, also called Javier, was a member of the Mexican national team to reach the quarter-finals of the 1986 World Cup, while Javier's (senior) father-in-law - and the grandfather of Javier (junior) - Tomas Balcazar, played in the 1954 tournament.
Balcazar scored against France in the '54 World Cup at the age of 22 - the same age United's Javier was when he netted against the French in 2010.
Jerry, Johnny and Wilson
South Africa 2010 was also ground-breaking tournament for brothers appearing at a World Cup with Honduras naming three Palacios brothers - Jerry, Johnny and Wilson - in their squad.
Jerry was a late inclusion for the Hondurans, who were making only their second appearance at the finals, after he replaced the injured Julio Cesar de Leon.
Wilson, who has played in England since 2007, was close to not making the tournament because he had injury worries of his own but was declared fit enough to take his place, meaning they became the first trio of brothers to represent a single nation in a World Cup.
There is another Palacios brother, named Milton, who also made appearances for Honduras, but his last game for the national team was in September 2006.
Jack and Bobby Charlton became the second set of brothers to win the World Cup, in 1966, 12 years and two World Cups after Fritz and Ottmar Walter had lifted the Jules Rimet trophy with West Germany.
Tough defender Jack spent his entire career with Leeds United and was called up to the England team just days before his 30th birthday, in 1965, before earning 35 caps in total. Bobby, meanwhile, played over 600 times for Manchester United and made more than 100 international appearances for England.
Both brothers played in all six of England's matches in '66 and Bobby scored three goals en route to the 4-2 win against West Germany in the Final.
Yaya and Kolo
One set of brothers that will travel to this year's World Cup are the well-known Ivorians; Yaya and Kolo Toure.
Kolo was recently diagnosed with malaria and missed their 2-1 friendly defeat to Bosnia last Saturday, as did Yaya who had a muscle problem, but both are expected to be fit for the tournament in Brazil.
The Toure brothers are no strangers to playing in the same team as they were both contracted to Manchester City for three years from 2010 to 2013, before Kolo transferred to Liverpool.
The duo played at the 2006 World Cup - the Ivory Coast's first appearance - as well as at the 2010 tournament.
