Clubs can sign as many as they like but you can only register 30,the dogs problem is they are overpaying duds like Thompson and nobody else wants themSurely clubs shouldn't be able to sign players UNLESS or until there is a position available.
So if you already have 28 players signed for the upcoming year, you should only be able to make 2 new signings until you are able to 'move on' one of the existing contracted players.
