The agent of former Barcelona coach Frank Rijkaard has again declared the Dutchman is ready to return to work.

Chelsea and Sunderland in England have been linked with Rijkaard in recent weeks.

"Rijkaard will think about all serious offers," Perry Overeem told Sportweek. "But it must be the right club, under the right circumstances.

"He would like to start again but it is not that he needs to get a new job. It must be a sporting challenge in a competition that appeals to the imagination."

Overeem also suggested his client - a former coach of Holland - would not be interested in a return to the international game.

He said: "All big European countries are interesting. Rijkaard is open minded in this. The only thing he doesn't want is to be a national team boss again."
