Yorke has been invited to train with his old club to prepare for Saturday's 'United Relief Live: The Big Red Family Day Out' at Old Trafford.

He knows Ferguson of old thanks to the three championships he collected during his time with the Red Devils and his status as a 1999 Treble winner.

And while time has aged them both, Yorke can see the fire still burning in the Scot.

"There is no sign of Sir Alex walking away despite all these rumours," said Yorke.

"People were saying he was going to retire when I was here and that was 12 years ago.

"He has made it absolutely clear that as long as he is in good nick, he will stay.

"Seeing him over the last two days I don't see him letting up."

Ferguson could yet end the campaign with a 12th Premier League title, although that would require Chelsea to slip up at Liverpool on Sunday.

Given United's next championship will be their 19th, surpassing the record Liverpool have held so proudly for so long, there are plenty on the red half of Merseyside crossing their fingers their team fails.

However, Yorke, who will be facing Ian Rush and John Barnes in a Rivals team that tackles a United line-up containing Andy Cole, Jaap Stam, Ronny Johnsen and Denis Irwin on Saturday, is certain such a feeling will not filter into Anfield's home dressing room.

"It is a myth the feeling they are going to throw it in. Professionals don't just turn up and throw games," argued the former Trinidad and Tobago star.

"There is a lot riding on the game for Liverpool in terms of trying to clinch fourth spot. They are also hoping to be in the Europa League final.

"They have to give themselves a fighting chance and winning breeds confidence."
