Ruddock said: "Sam Allardyce would be capable of sorting out all the problems that face Liverpool," Ruddock said. "What he has achieved at Bolton is nothing short of a miracle and he has done it all on a shoestring.
"You can only begin to imagine what Sam would achieve with a chequebook as big as the fat one Houllier has been writing from.
"Allardyce doesn't stand for any nonsense and it's clear his players are doing it for him. He's transmitted his own passion and desire to win to the team. That is what Liverpool need right now."
