After it was noted many people during the 2002 FIFA World Cup Korea/Japan™ watched the World Cup games away from the stadia and their own domestic televisions Impromptu gatherings made it clear, sometimes with hndreds of people meant there was a greter social component to the World Cup than had been previously recognised. FIFA introduced the FIFA Fan Fest™ became part of the Official Programme at the 2006 FIFA World Cup™ in Germany . Locations for the FIFA Fan Fests were large enough to accommodate many thousands of people, and gigantic LED displays broadcast the matches live. This allowed many fans unable to afford the price of match tickets the opportunity to cheer on their national teams with other supporters. The carnival-like atmosphere soon proved popular and thousands of supporters flocked to the sites to watch all the games.The FIFA Fan Fest™ proved the perfect place to watch all matches of the FIFA World Cup™ live, and to enjoy an exciting music and cultural entertainment programme, free of charge on matchdays.
At the the 2010 FIFA World Cup TM, the FIFA Fan Fests was expanded to include not only the South African host cities but 7 other cities around the world. Over six million football fans gathered to watch the tournament.
In 2014. The FIFA Fan Fests was held in each of Brazil's 12 host cities. 5,154,386 attended FIFA Fan Fests in Brazil during the World Cup, with Rio de Janeiro's spectacular Copacabana site attracting 937,330 which was the highest number in any individual city.
The 2018 FIFA World Cup™ , FIFA Fan Fest™ venues are located in the eleven host cities in Russia.

Researchers at Queen's University, Belfast have suggested the human vision system is unable to predict the trajectory of a curving ball through the air. If true, this means goal keepers are handicapped and rely on chance to save rocket shots from sharp shooters like Zlatan Ibrahimovic or Lionel Messi.
Goal keepers were asked to watch computer simulation of spinning shots of 600 revolutions per minute and predict how the spin would influence the ball’s trajectory. Even professionals failed to do this. Spinning balls do not occur naturally and the side spin on the ball produces something called a Magnus force. This accelerates the ball in a direction that humans simply cannot visually process and the skill of the keeper to make a save from a bending ball is based on an educated guess.
The Magnus effect was first described by German physicist Heinrich Magnus in 1853. It is a product of various phenomena including the Bernoulli effect. According to Bernoulli's principle, the pressure is lower on the side where the velocity is greater, and consequently there is an unbalanced force at right angles to the wind. This is the magnus force. Another variable is the formation of boundary layers in the medium around moving objects.
The boundary layer is that layer of fluid in the immediate vicinity of a bounding surface. In the atmosphere the boundary layer is the air layer near the ground affected by diurnal heat, moisture or momentum transfer to or from the surface. The Boundary layer effect occurs at the field region in which all changes occur in the flow pattern. The boundary layer distorts surrounding nonviscous flow. It is a phenomenon of viscous forces. This effect is related to the Leidenfrost effect and the Reynolds number.
The ball spinning through the air creates a whirlpool of rotating air about itself. On one side of the object, the motion of the whirlpool will be in the same direction as the wind stream that the object is exposed to. On this side the velocity will be increased. On the other side, the motion of the whirlpool is in the opposite direction of the windstream and the velocity will be decreased. The pressure in the air is reduced from atmospheric pressure by an amount proportional to the square of the velocity, so the pressure will be lower on one side than the other causing an unbalanced force at right angles to the wind. The overall behaviour is similar to around an aerofoil with a circulation which is generated by the mechanical rotation, rather than by aerofoil action. An experienced player can place a wide array of spins on the ball, the effects of which are an integral part of the sport itself. The way the ball spins and changes the air flow can really confuse the opposition," says Dr David James, of Sheffield Hallam University, Centre for Sport and Exercise Science.
The surface of the ball is affected by its shape and stitching which increase traction between the ball and boot. The Adidas Telstar 18 has six textured panels. These are not stitched, but seamlessly glued together. This makes the ball a lot more round with better sphericity, so it behaves more like a billiard ball than the traditional bladder. Changes in the design of football boots including improved traction on the boot upper and greater sole stiffness combine to give better control of the ball by the player.

Professional footballers second main source of income is their individual sponsorships, after the salary they receive from their club. Brands seek to lock down key players with financial incentives and different conditions which makes it unusual to see football stars change their sponsors during their professional career. This does not mean it has not happened but it is the exception to the rule. In the lead up to the World Cup much store is put on the key sponsored players to show case the new range of boots.
At the FIFA World Cup TM 2014, the first goal of the tournament was scored by Marcelo Vieira (Brazil), only he netted into own goal. Not that unremarkable, but the captain of Brazil had recently changed his sponsor which put the payer under the spotlight.
Playing for Real Madrid he was sponsored by Nike, then at the World Cup 2014 he had become an Adidas player. Was the own goal a serendipitous event, or the revenge of changing sponsors, who knows?
For FIFA World Cup Brazil 2014 Nike signed six of the best players in the world including the top ranking Cristiano Ronaldo (Portugal).
Nike also sponsored 10 national teams including: Brazil , England, France, Portugal, Netherlands, Greece, Croatia, USA, Australia , and South Korea .
In total, 171 goals (five own goals) were scored by 121 players during the tournament, with 135 goals scored in the first round. In FIFA official records goals scored from penalty shoot-outs are not counted. Sixty-one (61) came from players wearing Nike cleats. Nike's best-performing boot (21 goals and 65 assists) was the Superfly IV as worn by Chile's Alexis Sanchez and Switzerland's Xherdan Shaqiri; Hypervenom 13; Vapour X 10; Magista Obra 7; Tiempo Legend V 6; Vapour9 2; CTR 360 III 1 ; and Magista Opus 1. Brazil's Neymar da Silva Santos Jr., (Neymar) wearing Hypervenom, Nike’s top goal scorer with four goals and Nike’s Miroslav Klose (Germany) netted his 15th World Cup goal to tie for the title of all-time leading World Cup goal scorer.
Adidas was the major sponsor of FIFA World Cup Brazil 2014 . The German Company outfited nine national teams. (including four of the favourite teams i.e. Spain, Germany, Argentina and Colombia.) These were: Argentina, Bosnia and Herzegovina, Colombia, Germany, Japan, Mexico,Nigeria, Russia and Spain.
Fifty-seven (57) goals and 54 assists came from the boots of players wearing Adidas cleats. Adizero (38 goals); Predator Instinct (15 goals) ; Nitrocharge BP (3 goals) ; 11Pro TRX (1 goal). Germany's Thomas Müller (5 goals) and Argentina's Messi (4) wore Adizero to become the top scorers for the three stripes.
James Rodríguez (Colombia), was awarded the Golden Boot for scoring six goals wearing Adizero boots.
The Adidas-sponsored FIFA World Cup TM finals, featured two adidas sponsored clubs, Germany and Argentina. However, when Germany’s Mario Goetze volleyed in the winning goal. He was wearing Nike’s new lightweight “Flyknit” boots
Puma-sponsored players scored eight goals with six assists. Evopower 1 (6 goals) and Evospeed 1.2 (2 goals) . Puma unveiled novel colourful versions of Pumas’s evoPOWER and evoSPEED football boots, with the right boot in pink and the left boot in blue.
Goal scorers wearing the Tricks boot included Ghanaian captain Asamoah Gyan with two goals; and one goal each to Mario Balotelli (Italy) was paid an estimated $6.9 million to wear one blue and one pink Puma cleat and went on to head Italy's winning goal against England.
Others included: Olivier Giroud (France), Vedad Ibisevic . Oribe Peralta , Rafik Halliche , and Diego Godin .
Best of the rest. Tim Cahill (Australia) wore Warrior Superheat soccer cleats when he volleyed a screamer into the net of the Netherlands.
The two Brazilian Goal Keepers: Júlio César and Jefferson de Oliveira Galvão (aka Jefferson) wore ASICS soccer boots during the FIFA World Cup Brazil 2014.
