Welcome to the forum slick z your team seems good enough for. Your level . Use the tactics wisely don't go for hard attacking for a full game no wonder your players are tired . Try normal then attacking then defending check out how your team play with those orders . My advice would be its a big learning curve at 1st but at your level that won't matter too much if you get it wrong . Part or most of the fun is trying new things and learning from them so enjoy
