Nope he was a nordeus gen on first day of new season. It's easy to find fast trainers and the key is not only their price, but their price compared to their stars a 15m value 4* 18 yo player will train surely faster than a 5* 1 sp away from 6* 18 yo 15m value. Not only because the 5* has more stats, but mainly cause the weaker one has already the same value. Ofc, you might prefer the 5* since he has about 75 sps more than the weaker, but if you plan to train SA or nee roles, than the 4* will eentually be a lot faster. It will require just about 40 greens to reach the same quality of the 5*, and at that point his value will be about 22m tho.
