As talk regarding Jose Mourinho's potential move to Old Trafford continues, former Red Devils striker Yorke believes club legend Giggs is the only man capable of turning things around after the failed Louis van Gaal era.
"For Manchester United now there is no candidate out there," said Yorke, speaking exclusively to 888sport.
"If they don't either this season or next season then Giggs won't be around anymore because he has served his time.
"If he can't make the step up after three years after seeing all he has seen then when? After ten? There is only one candidate. There is no question in my mind who should get the job."
