i want to change a training position of one player

for example, one of my best players has two position. DML,ML..

so i started training another position DMC.

but these days i want to teach MR, cause i dont have any MR more for substitution.

here is no way to stop current training position.

will that be possible??


ANd i have one more question.
what happen if i put a player in wrong position? does his stats become lower? or would he get exhausted easily??

im really sorry for bad english! thank you

I don't think you can stop the current training, but don't just take my word for that.

Regards players in wrong position, the player won't perform to their full potential, but it would very much depend on how far out of position they are. If MC at ML for example, his performance will only be slightly down. But if they are far out of position (DR at ST), they will be down quite a lot.
