I know Gerrard dives, famously infact, alot of the time he's highlighting a foul though, not that I'm excusing it.
The video of Torres looks like he might've get studs into his right calf? He goes down to easily sometimes though admittedly, it may have something to do with the fact he gets the shit kicked out of him for 90 minutes and if he has the audacity to complain he gets a yellow. (See the Mascherano "incident" at Old Trafford)
So yes, Gerrard dives, as does Torres, Rooney, Van Persie, Ronaldo, Messi and this fella
