Excepting a stunning four-goal display in United's 6-1 rout of Arsenal at Old Trafford last season, Yorke struggled for form.

The forward clashed with Ferguson after arriving back late from an international trip last summer and believes it is time to concentrate on club matters after only scoring 12 goals last season.

And Ferguson wants to see the striker get back among the goals for the champions.

He said: "Dwight has got to put everything behind him and show that he wants to stay here. I don't think there is any problem on that score.

"But there has been some interest in him and it is something I will only pursue if it is in our interest. We are in no rush to do anything.

"If Yorke finds the form of two years ago you wouldn't ever want to sell him. He is one of the best in the business."

The 29-year-old has endured a rollercoaster summer with Trinidad and Tobago.

He was dropped and then reinstated for the World Cup qualifier with Honduras after failing to turn up for a friendly against Panama, later citing his sister's ill-health as the reason.

The Caribbean side saw their hopes of qualifying for the 2002 finals in Japan and South Korea fall away when going down to the USA.

And despite scoring in a win over Bermuda on June 25, Yorke decided to call it a day just four days later.
