Tagseth scored in victory over Blackburn Rovers on the weekend.
Gerrard told liverpoolfc.com: "I thought he was excellent all over the pitch. If you watch Edy closely, not only is he a wonderful passer, he has got unbelievable energy, he does all the dirty work, he gets on second balls, he runs back.
"He's a quiet kid; we're trying to get him to come out of his shell. He's got an unbelievable future if he keeps working the way he does."
