Eriksen is back after suffering a cardiac arrest at last summer's Euros.
Hjulmand said: "I've been following it all closely. I've been to London to see him and feel he's good and he's fit. He is really physically very, very fit, and the level we have all seen him play with has been impressively high.
"The way he acts on the pitch is recognisable. He is attentive, he wants the ball and his passes are crucial.
"He was the best player of the match in the match I saw in London (against Burnley), so he is in a really good condition."
