Blue Lock 1 by Muneyuki Kaneshiro

A mad young coach gathers soccer players from across the country to compete in a series of bizarre challenges in a high-tech colosseum he calls Blue Lock. It's a no-balls-barred battle to become Japan's next top striker, in this Squid Game–meets–World Cup manga, now available in print! Anime coming soon! Are you the world's top egoist? After a disastrous defeat in 2018, Japan's soccer team struggles to regroup. But what's missing? An absolute ace striker. The Football Union is hell-bent on creating a striker who hungers for goals and thirsts for victory, so Blue Lock -- a rigorous training ground for 300 of Japan's best and brightest youth players -- is created. To survive this battle royale, the last striker standing will have to out-muscle and out-ego everyone who stands in his way!
