After seeing a deadline-day bid for Villarreal striker Giuseppe Rossi fail, and sending Robbie Keane on loan to West Ham, Redknapp is keen for Jermain Defoe, Peter Crouch and Roman Pavlyuchenko to start delivering fast.
"They are our strikeforce now," Redknapp said.
"We are relying on those three to produce the goals. Van der Vaart is the only man who has got his ratio of goals. "We need the strikers to start scoring regularly as well."
