It has crossed my mind a couple of times, with henry getting better and better and no defence seemingly able to stop him let alone a single defender, is he unmarkable?
The closest Ive seen to anyone marking him out of a game was in the OT debacle in about september, when Ferdinand had him in his pocket for the whole game, but Arsenal were very defencively minded that day and most of what he was left with was scraps and was playing with his back to goal and contesting headers. Considering that everyone has off days aswell, on form who would stop Theirry Henry?
