That is normal. One player is somewhere around your average team rating. One is poorer or inferior player, the one which needs no tokens to sign. Normally i sign him and sell him off. And i keep the good player.

I am not concerned about this too much though. What i am concerned about is that i have to sign one player for around 21 tokens. I have spent money and time for my own players to develop, and now when i want to promote them to the senior team 21 tokens.

Nordeus does use some sneaky tricks to swipe tokens off of you.
