Friendly v training

[becks23]

I'm probably doing something wrong, but I'm not seeing the right improvements. I win friendlies, but the players who do not interest me always growing better than others.
where am I wrong? I always put a weak formation and the players that interest me like forward.
Players gain 1-2%, I don’t think is right way 🤷🏻*♂️
someone explains to me how to do it? even in private. thank you

Put 8 crap players and 3 good players in striker positions. It doesn't matter if they are not attackers.Your goal is to give the mvp to 1 of the 3 players you want to develop not to the 8 crap players so put 8 players and move the to the defence and they 3 good players in offense. For you to see a big change to your players you need to have lots of friends and you need to organize 30+ friendlies if plus you will get a lot of blues and greens back. So put your good players high up in the pitch organize lots of friendlies and you will create mutant players
