The forward has bagged three goals in four games since his big money summer move.
Morgan said: “He works hard and he's always in your face.
“He causes defenders trouble and makes them think, so he's a nightmare to defend against.
“He's a presence up there and works hard. He can hold the ball up and win balls in the air. He's very good with his head and that's shown with the three goals he's scored so far.
“He's definitely an asset to the team and if he keeps putting in performances like that, everyone will be happy."
