The Reds have been woefully inconsistent in the past month, picking up just six points from their last four Premier League games.
Tony Pulis' Stoke side was the latest club to hand an emphatic defeat to Liverpool, outmuscling Brendan Rodgers' team in almost every department during their Boxing Day clash, finishing with a 3-1 victory to maintain their 16-game unbeaten run.
Speaking to the DailyStar.co.uk, Ruddock believed the Reds lacked aggression in midfield and he singled out Tiote as the right man to plug the gap.
"They need to sign him [Tiote] to break down play and give the freedom to [Steven] Gerrard and [Luis] Suarez," he explained.
"Liverpool are too nice, they don't have enough men. These days Anfield's a nice place to go and play - you're not going to get run around or get kicked off the park."
Reflecting on the club's successful past, the former defender pointed out the importance of the job performed by the likes of Graeme Souness and Ronnie Whelan to their silverware-laden years.
"You used to have Graeme Souness or Ronnie Whelan, people like that. They need someone like a 24-year-old Souness, Roy Keane or Paul Ince," Ruddock said.
"They have to have a plan B where they can all roll up their sleeves and get stuck in."
Liverpool play relegation-threatened Queens Park Rangers in their next Premier League game.
