Maybe. Not so sure any of the Segunda Division clubs are willing to make him one of the best paid players in the league when he has played minutes equivalent of 11 full games in the last three years. Most of the clubs are also in a horrible financial situation. But I guess maybe Zaragoza could...
That would probably be what the club prefers, but who are going to want him after that year in Cadiz?
No idea, but a lot more than he's going to earn in the Spanish second division or some lower-table team in Turkey.
No club will be willing to pay anywhere near what he earns in Brighton so it is probably easier said than done. If he'd accept to terminate the contract for half or so of his remaining wages, I think the club would take it.
