This is how academy coaches are asked to operate. Results arent relevant, player development is. Players themselves will bring a competitive edge, that is normal, bir coaches are looking to see players learn certain things in training and then implement them in a game.
One of my first experience was in Stokes academy. I was helping with some dev players they had. The lead coach asked me to work on certain things with them over a 3 week period and then we would put them in a game. It was all about controlled possession. I did 9 sessions with them, all unopposed, and then they went in and played the game. They got beat 3-1 but the lead coach couldnt have been happier becuase they had so much control of the ball and were able to keep it. That was a baseline for the next phase of their development.
