Thinking about it, that crazy SOB Zatman's suggestion isn't completely without merit; if he manages to clatter Torres before he reaches the box - taking the red card and free-kick - and if Barcelona then manage to defend the resulting free-kick, it's even-steven (albeit now with an outfield player in goal, but hey the game's nearly up anyway) for the dying minutes and they're still in with the slimmest of slim chances of maybe getting a goal. Like, über-slim. But still better than no chance.
Like someone else said, any striker should be putting that away. If Valdes comes out the box to clatter him Torres either chips him or gets round him even easier than he would in the box.
