Are my players overwork ?

[Chris Rath]

Is it advisable to sell my expensive players towards the end of the season ? So that I can get better players at the next level ?

Your players are already even quite good for level 2. With the current team you should still do fine a league higher, too. If you have many tokens and fun at power training (as it seems ), sell the old one like you have planned.

Now i have rest players that are not gaining much progress and continue to power train the others that are still having good skill progress.
