Hulk blasted an absolute rocket from the corner of the 18-yard box in the 7th minute of Porto's win 3-2 win over Benfica, putting them ahead of their O Classico rivals and atop the Portuguese Liga table.
Hulk's shot was timed at 108 km/h (67 mph) and probably would've taken Benfica goalkeeper Artur's (no relation to our friend Artur Boruc) arm clean off if he got a hand on it. As blistering as it was, it was still nowhere near as fast as unofficial record holder David Hirst's 114 mph volley off the crossbar against Arsenal in 1996.
Video of Hirst's effort this way...
Of course, Hulk did actually score with his shot, so I think he wins.
