According to this poll, Higuain is number 2. To answer the original poster's question, I would never 'bet my house' on Higuain scoring - because while he is capable of scoring from insane angles, I'm never sure which Higuain will turn up. His performance in the second leg of the Supercopa this year was terrible. I watch a lot of Madrid matches and I know for sure that if they had a better forward than Benz, Higuain would've had a fraction of the minutes he's got.
I'm always surprised as people don't seem to take form into consideration at all. Some players can do insane things while they're on form but what's the point if they're only on form for 3-4 weeks in a season?
