As a new team its best to invest in 3-5 young trainable players rather then on a 30yo that will be nearly worthless in a couple seasons.
You want to create as much player quality and value from training as possible. The primary keys for doing this is having a good training plan (which skills will be trained) and how good are your trainees from the start (skills, potential).
What you do with those players once they have been trained and are worth more is up to you. Best to read thru this first
