Ohhhhh, I see now, it's the timeframe that matters is it, not whether he's actually scoring against the big teams or not. That'll be why he had the better scoring record against ManU than RvN did against us. No wait, I guess you just manage 20+ prem goals a season for the last 6 years by only scoring past the rubbish sides.
Honestly, I really can't be bothered to trawl google for hours to find his entire scoring record over the years, youtube was simply a lot quicker to do. All you have to do is type "Thierry Henry + [club name]" and lo and behold, you'll find at least one goal.
Him being a big-game bottler is utter, utter *******, and it annoys me that people continue to propogate that myth about him. He scores in big games just as much as any top class striker out there: ie. Not every single one, because he's not the second coming, but enough to count. As I said, you don't score that many goals by chance.
EDIT: I never thought I'd agree with BaZ, but there you go, he got it spot on.
