Henderson capped his performance with a deserved goal.
"You just put it down to him," said the manager. "When I came into the club, I had always heard he had a brilliant attitude to learn - that's what I've found since I have come in.
"I think it was a great buy by Kenny [Dalglish] to bring a player of that quality in. As a young player that's hungry to learn - he's 23 years of age, he's 6ft1in and he can run all day, he's technically very strong, tactically he is understanding when to press and when to drop in.
"His goal, technically, was a wonderful goal. He's a terrific player, he just needs confidence and constant work. He has been outstanding for me.
