Ok, I see I should write new msg here.
So like I said before (propably to your U21 manager) they will play 30' minutes in all my games (meybie in some really improtant they will be in youth team), becouse I want to create fantastic players to my team and yours NT. I hope I can do that.
Today You they will play 30' minutes in league game, so You don't need to be worry about that.
Regards.
