@Celtic why should he powertrain now?
Next season this 4* will become 3* and less valuable. Moreover, these players (fast trainers aka nordgens) are quite expensive on low levels. Isn't it better to have next season older (up to 30 years) player which is worth same as that 4* which will be 3*? Do you know how much he need resources and time to get that player up at 5*? That is completly pointless. Low levels need more financial-wise strategy. Grown players are much better choice. Moreover, 5* nordgens for low levels are too much expensive. Would you pay 1M for level 1 nordgen if your start budget is 700K? LOL That is why i sell them, it isn't always easy (waiting for buyer) but pays off for sure.
Trust me, i've went through these low levels 6 times and i know what i'm talking about and why. Moreover, there is mine guide about takeover of new team from level 1, read it, it could help because there is info how to play at level 1.
There is also trophy room of mine low level team.
