Look Incubo:
If the black dots are Lecce players, and red dots Juve players (Treze, Camo and Appiah - the blue one is the ball obviously), you can clearly see that Trez was not in an offside position. Camo was walking back, and appiah was on the left side of the pitch, therefor Camo couldnt possibly have obstructed line of sight, and if the unexperienced 21 year old S&M goalkeeper had payed his attention to the ball (which was nowhere near Camo) it might have not been a goal.
Anyways, he has nobody to balme but himself, the rules clearly say it wasnt an offside OFFENCE (happy now?)!!!
