Yorke deal done last month 

Sydney FC chief executive Tim Parker says the club made crucial decisions such as keeping star Dwight Yorke before last month's A-League grand final.

Parker was responding to reports Yorke's agent Simon Bayliff had only confirmed his client's return this weekend.

"It's very sweet of him (Bayliff) to say so given Dwight's on a two-year contract, it's not like there's a lot of issue about it," Parker said.

"He's been off in Manchester apparently freezing his nuts off in the rain and snow and rang our chairman last week to say how miserable it was, he'll be happy to return I expect."

Parker said Yorke would be back in Sydney soon after Trinidad and Tobago's World Cup campaign is over.

He said the continuation of Yorke's deal had ceased to be an issue once the club had reviewed its first season expenditure and appraised the former Manchester United star's value.

"We examine every area of our business as you would any business and clearly the areas you look at first are the areas of major cost and, along with the cost of playing at Aussie Stadium and the salary bill, then clearly the marquee player and the coach are pretty up there as major costs.

"We looked at it and we questioned it pretty hard and we decided that it delivered value and that it should stay."

But Parker said he couldn't guarantee Yorke would line up for Sydney next season if he stars for Trinidad and Tobago at the World Cup and the A-League club is approached with an offer from a wealthy club.

"We're playing a global game that has a global value on it.

"If Dwight was to star at the World Cup in a way that suddenly made him a very very valuable proposition for somebody else and another team was to come to us then we would have to review it.

"The economics say you would simply be daft from a business perspective not to look at a serious offer."
