( CNN ) -- More than a week into the tournament , diehard World Cup fans are losing sleep and falling down on their jobs as they yell at their TV and computer screens . For those who have n't caught football fever , the enthusiasm and the sport may leave them befuddled . But behind the World Cup there are stories that can speak to everyone . 1 . It 's a family affair . When Germany and Ghana face off Saturday , two brothers will as well . For Jerome Boateng , Germany defender , the match will be especially loaded . He 'll be playing against not just his half-brother , Ghana 's midfielder Kevin-Prince Boateng , but also their father 's home country -- a place he 's never even visited , according to FIFA . The brothers have reportedly ceased contact during the World Cup to keep their heads in the game . But will they hug on the field ? And who will family members , if they 're sitting in the stands , root for ? Hopefully cameras will swing their direction so we can find out . 2 . Seeking light amid the darkness of violence . Nigerians love their football . In fact , market researchers at Repucom determined it 's got the world 's biggest football fan base out there . More specifically , the firm 's study shows 83 % of Nigerians are interested in the sport and 65 % participate . Those figures dwarf other nations , including World Cup host Brazil -- where 67 % are fans and 28 % play . So football fanatics from that African nation will certainly have a vested interest in their team 's Saturday World Cup game against Bosnia and Herzegovina . And given the tragedy that befell football watchers last Tuesday -- when a Boko Haram-backed explosion rocked a viewing center in northeastern Nigeria , killing up to 21 sports fans -- a win for Nigerians may be extra sweet . 3 . It 's getting hot in here . The heat and humidity in Brazil , some locations more than others , have been taking a toll on players . Dehydration . Cramps . Even hallucinations . There have been complaints about it all . Some have attributed a rash of injuries to the conditions . The venue in Manaus , an Amazonian city , has been especially brutal . A quick online look at temps Saturday show that Argentina and Iran may be playing in 95-degree ( Fahrenheit ) conditions . The good news for them , though : humidity will only be at 45 % . Conditions for Germany and Ghana , on the other hand , look like they 'll be 67 degrees with 76 % humidity ; Nigeria and Bosnia and Herzegovina will face 86 degrees and about 61 % humidity . The 2022 FIFA World Cup will be played in Qatar , where average temps this time of year exceed 100 degrees Fahrenheit . 4 . What 's in a name ? The Three Lions ( England ) may have gone home , but the Desert Foxes ( Algeria ) are still in the game . Each team in the World Cup arrives with a nickname . Some seem inspired : Clockwork Orange ( Netherlands ) ; the Coffee Growers ( Colombia ) ; Blue Samurai ( Japan ) . Others are less so -- though at first glance they may fool you : Nationalmannschaft ( Germany ) ; Sbornaya ( Russia ) , and Team Melli ( Iran ) . The translation for these three : National Team . Really ? That 's the best you 've got ? There are three games Saturday . Here 's who is up : . The White and Sky Blue ( Argentina ) v. Team Melli ( Iran ) National Team ( Germany ) v. Black Stars ( Ghana ) Super Eagles ( Nigeria ) v. Dragons ( Bosnia and Herzegovina ) 5 . Kicking politics aside . The World Cup tournament , which draws together 32 nations , puts the sport before politics . That mindset remains year-round for Dan Gaspar , the Portuguese-American goalkeeping coach for team Iran -- which goes up against Argentina . He took the job in Iran to work with his friend and former colleague Carlos Queiroz , the football team 's head coach . It was a decision that went against the advice of most . After all , was n't Iran supposed to be America 's enemy ? `` Sports is my life , '' Gaspar told CNN 's Reza Sayah . `` When I came to Iran it did n't have anything to do with political reasons . My personality is one of adventure and curiosity . I wanted to experience a culture in a part of the world I had never been to . '' Iran has surprised him . His impressions before coming have n't matched reality . `` When you listen to the news and you read the news , you see things . Sometimes during commercials I step off my couch and look out of the balcony and it 's not what I am seeing , it 's not what I am reading , it 's not what I am hearing , '' he told Sayah . `` If I would 've listened to the experts , and my friends , and family , I would have never been here in Iran . It 's been part of my life for three years and the memories will last a lifetime . '' Brazil 2014 : Score updates and schedule of matches . World Cup by the numbers : Who 's in , who 's out ?
