I'd say that he's an option, not a particularly good one though. As for being a '100% er' well i'd say most of them are, they just show it in different ways, not everyone can chase down and run along the back line, and thank god for that, and giving 100% is sort of a requisite for a footballer, i don't think that it raises the effort rates in training, if so, then we're in bigger trouble than i thought.
