Thought Buffon went for that ball the way he always does, which is to try and make an actually tackle, unlike what many keepers do.
Didn't think he was slow off his line and don't have a problem with a keeper trying to be very precise so as to minimise the risk of the red card.
If I was going to criticise Buffon on that goal at all, it would probably be for coming out at all. Think he may have had a better chance of stopping Drogba if he'd just accpeted the one-on-one situation and tried to make a save from Drogba.
Still, it's not one that I'd hold against Buffon at all.
People are just looking for stuff because he hasn't been playing well lately.
