level 1 also trains FT and stamina effectively. but for other trainingtypes a higher level indeed is very recommended. level 4 seems to be okay if he can be afforded.
I also like to add that it's not just the pops that are important. Players you train do get training and become better, no matter if you realy 'see' it (pops) it's very possible that a player for instance is a 4,1 and is shown as a 4, and after training is still shown as a 4, but has become 4,4, in which case he will also play his games as a 4,4 and not the 4,1 he had before.
So even without pops, the players do get better...
I just wanted to make this clear as many users seem to think a player only gets better when he realy pops.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
