"I'm going to put him under pressure and say that he can score more than 15 goals for us," said the Liverpool manager.
"I am convinced he can do that. When I say 'more' maybe I mean 20, maybe 25, I don't know. But more than 15 because he's a very good player and we can create a lot of chances. He can score goals with the quality of our players.
"He can score goals himself but he can create opportunities and assists so maybe he can be worth even more goals to us in that way."
