Ruddock believes Liverpool are most in need of the Ivorian enforcer.
"They need to sign him [Tiote] to break down play and give the freedom to [Steven] Gerrard and [Luis] Suarez," Ruddock told DailyStar.co.uk.
"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.
"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.
"They have to have a plan B where they can all roll up their sleeves and get stuck in."
