Best way to have a 7 star team

[Der_Ryan_M]

Few days ago I bought this guy:




He is an extremely fast trainer, which I don't find a lot of, as it is hard to spot fast trainers in high levels. I want him to be my main striker in the future, train him SA this season and power train next season to get him ready and up to 7 stars when he is 19 years old.

What do you think about this idea? Or should I rather buy an 18 year old 5 star guy next season and train him to 7 stars with less green packs, but therefore less impressive skills... (Which would develop over time)

Or a 3 star 18 year old next season and power train him? (He would have similiar stats but 1 year younger, but keep in mind, that there is no guarantee that I find a fast trainer early in the next season...)


How many rests do you even need to train from 3 to 7 stars?
