Getting rid of players

[santiago90c]

Hi everyone, I'm currently training Real Madrid Castilla, this is my second season and we got promoted to LIGA Adelante (the Spanish 2nd division), the thing is I got sent a lot of players from Real Madrid ''C'' (which play in a lower division), but most of them are very ****** and I cannot get rid of them, I got like 25 players not registered for the LIGA Adelante season and I did offer them to other clubs and got no offers, so then I offered them mutual termination and not even one agreed, even though they haven't played in a year and a half... Is there any way I can get rid of them? I ask this because of the wages problem, as long as I have these much players it's pretty hard to get new signings, or at least decent new signings.

I've also tried sending them back to Real Madrid ''C'', but that manager keeps sending them back to me.
