Gerrard has praised the attacking qualities of the Liverpool centre-back after his goal against Blackburn yesterday.
"He's terrific in the air and I know that if I put quality deliveries in there, we'll get goals from set-pieces. The slight disappointment is that we never got one or two more," said the skipper.
"It's certainly a weapon in our armoury that we know we have to keep working on and goals will come from it."
