Cardiff's Jobi McAnuff has completed his move to Crystal Palace after signing a four-year contract with the London club.
The midfielder, 23, had previously said he wanted to stay at Ninian Park where he had one year left on his deal.
Cardiff owner Sam Hammam told BBC Wales Sport last week that the two clubs had agreed a fee of around £600,000, but the final figure is undisclosed.
McAnuff scored three goals for Cardiff after joining from West Ham in August.
"I'm very sorry indeed to see him go," said Hammam, who said a chunk of the transfer fee would go towards paying the remaining instalments on McAnuff £400,000 move from the Hammers.
"I've known him since he was 10 years old when he was at Wimbledon. I know his family and I've been to their home.
"He's one hell of a player and it is a major loss.
"But as I've explained before, we're going to have to create a pool of money to give [new manager] Dave Jones.
"Quite a few of our players are on high wages and we have to get them out before we can get people in."
