"I know he is not a goalscorer yet but he does give you so many options. I am sure he will score goals and he showed that for Southampton with 16 goals last season. It is all about confidence," said Eriksson.
"When he played for us he did a very good job. He is still young. He is not very experienced but every game he plays for Liverpool he gets more and more experience.
"It's a pity that he is being booed like that. I would ask the fans to leave him alone. He will not get better by being booed. He's honest and hard-working. Against Austria he covered more ground than any other England player. That's very strange because normally a centre-forward doesn't do that, but he did."
