"It's always nice to see Liverpool players score goals, whether it's Robbie Keane, Dirk Kuyt or Sami Hyypia," he said.
"Robbie's been working tirelessly and he's kept on going. We know the quality of the lad, that's why we brought him here.
"If you speak to him he may give you a better answer, but for me, he's never been lacking in confidence.
"We've had no doubts in Robbie's ability. His work rate and commitment and what he adds to this club is immense. We've had no doubts about him. We know what he's capable of."
