I can´t buy a new player

I paid recently 21 tokens for one player, but he disapeared.

Why is that?

Uhm, more information might make this clear.

Signed players only disappear (get sold off) when you go into debt, and even then it gives you a warning before that happens.

Also I don't know if you realize you have to scroll down to see any players over twenty two, as well that is how the most you can have signed at any time.
