Beyond settling in and before his injury which has clearly lost him a yard of pace: hero, during settling in and after his injury: flop. People will say we never saw the best of Juan but during the period when he was good he was amazing and scored goals off little or no service.
For me he will join the likes of Savo Milosevic and Ian Olney as players who scored goals and will be remembered for doing so, but he isn't in the same bracket as Yorke, Saunders and Withe.
