Gk training is good for newcomers

Nope.
Coach has high wage and return will be very small.

Not that much higher wage compared to being able to train players up to a sale to 3-4 m eu in 3 seasons

you can eventually make some money if you buy 16-17y gk and sell him after two season of training if he has good talent

any other keeper training is not profitable and thus waste of training slot
