@jolynehoestar When they put the emphasis on the striker I started to believe that this will be a manga moreso about the mythos and fiction surrounding football rather than the technical details of the sport. Then they started talking about being a selfish forward (which some are, whilst others are more focused on creating plays).
After all the strikers are who tend to be the most "hype" for the fans watching at home. It does not mean they are the most important in the game, every position has its own role, but they are the ones associated the most with scoring goals.
Giant Killing is the best football manga currently IMO, and whilst I love the art of this one I doubt I'll like the characters and football as much.
Funnily enough I think they could get a similar form of death game by simply making a slightly fictionalised version of the European clubs. They really love stabbing eachother in the back haha. Plus there's enough dirty money there to make Scrooge McDuck jealous.
All in all I suspect this will be a shounen manga which focuses more on a fantastical version of football than the actual sport, and which is going to heavily favour Japan's odds despite prior history. It would honestly be a surprise if this didn't end with them winning the world finals and the intergalactic football league as well.
