You will never be able to play like X person from X tutorial, each manager have his own style and is quite impossible to explain you all his playing style.
Is good if you have moral and condition so good but you are level 21, how can you play with a player on an illegal formation... you are losing a lot on defensive line by playing like that.
Look at your players notes, the worst from all is the DL who is playing out of his position (DC). Fix that and play few games and let us know!
The problem now is that your players are already in a bad form so you can't change everything over the night... Good luck!
