The 19-year old winger is emerging as a key player in the Reds' race for the Premier League title and his performances at club level could see him selected in Roy Hodgson's 23-man squad for Brazil 2014.
If Sterling happens to receive that call, Danish centre-back Agger suggests he is well-placed to contribute positively to the Three Lions cause in world football's biggest tournament.
"He can handle the pressure. Otherwise, he would not play for Liverpool. It is a fantastic opportunity for him," he told Danish daily Politiken.
"In case he continues like he is doing right now, I can't see any reasons why he should not get a place in the squad for the World Cup.
"He is a big talent and got qualities that England need.
"Everyone can see that he is very quick and he is technically skilled, too. He has got experience from the best league and that is what really matters for a young player like him.
"To come on and get some matches to prove yourself. In any case, he got what you need to deliver."
Sterling made his England debut in a friendly against Sweden in November 2012 before earning his second cap in a 1-0 win over Agger's Denmark in March this year.
