Yeah, it's hard to tell really, Arsenal were themselve the recepient of some balant fake injuries to waste time (against Villareal). But for me, it's more unsportsman for people to fake injury (which I thought was the case here, from what I saw, Eboue was about to get up, saw the ball had travel down field, then rolled around again). I'm neither a Tottenham or Arsenal fan, so I'm just stating my prespective of the incident.
I'm more pissed off about serial divers and hand ball specialists (which is seemingly on the rise these days) and people that rolled around in the ground seemingly in pain, then sprints all over the pitch normally after 30 seconds (if they are tough enough to run around after an injury, then they must be tough enough not to roll around in seemingly agony - eg. Del Horno style).
