Aston Villa striker Darren Bent is set to make a loan move to Brighton in the next 48 hours, according to Sky sources.
Juan Cala wants to find 'another club ASAP' and believes Cardiff have acted without respect towards him.
Brighton have signed defender Aaron Hughes on a free transfer after his QPR exit.
The 34-year-old former Newcastle, Aston Villa and Fulham centre-half has agreed a one-year deal to become new Seagulls boss Sami Hyypia's first signing.
Hyypia told the club website: "We wanted to bring another experienced defender, and Aaron fits the bill - having played at Premier League, Champions League and international level.
"I have played against Aaron a few times during my time at Liverpool and also for Finland, and I know his qualities and what he will give us.
"He has a very good footballing pedigree, is an intelligent player, and he has a great mentality and good approach to the game.
"He has that experience I wanted to bring into the squad, which alongside our other senior players, will help our younger players continue to develop and progress in the first-team squad.
"Overall, we still have some work to do in terms of recruitment, and we are all working hard to do that. This is a good start and Aaron is a great addition."
