Yeah, I disagree Hanglund is better than Henry. Hanglund's mistakes are less obvious to the naked eye, but they are just as frequent. On the upside, he is nowhere near as physically dominant. Statistically, Henry lead or was near top in a lot of defensive stats. Hanglund has a better nose for goal in the attacking end, but that's small compared to what your expecting from a CB.
I'm not certain Henry will ever be a starting prem defender, but 10 years down the line I'd put my money on him turning into the better player.
