It wasn't Moriyasu's plan to call up U21 B-team players. The J-league clubs refused to release their main players. Unlike most of the Asian countries where local club football is almost dead and people only care about national team matters, Japan has a real professional football league that has higher average attendance than the likes of the Dutch, Belgian and Portuguese leagues. I'm just saying it's not a fair metric to judge Moriyasu based on the results of pointless games that were competed by non-first team players. Zico and Zach always fielded the same players but the combined World Cup record of the two is 0-2-4.
