Why is he expensive?

Why is he expensive but only 3 stars? Should i buy him?

[Sherifon]

he is super trainer !! he trains very fast but better for you buy a 5 star player.
higher value = faster training

[nikolgiorgos]

Definitely NO. Don't spend all of your money if you don't know anything about training. Try to be more comfortable with the game, earn some money and after that buy a fast trainer. If you want to improve your team, with the same money you can buy 2-3 4* players 24-28 y.o.

As they already said, he is nordgen, young talented and expensive player who has very fast growth. Token buyers use them much for power training.
For that money you can buy 3 or 4x 5* players on your level (2). So if you don't buy tokens for power training, then better buy few 5* players .
