It refers to the disallowing of a goal scored by Roma versus Juventus in a crucial match for the 1980–81 Serie A championship.
The match still remained tight until 10 minutes before the end when, following a move by Roma started by Carlo Ancelotti, the sweeper Maurizio Turone headed goalwards a ball played to him by the forward Roberto Pruzzo.
However, the linesman signaled to the referee, Paolo Bergamo, that Turone was offside and the goal was disallowed; the match eventually ended 0-0.
The disallowed goal gave rise to a huge controversy that endures in anti-Juventus circles - such as in the strong rivalry with Roma.
In the following years, conflicting opinions, projections with new technologies and alleged manipulation of slow motion continued to come in succession; in any case, from then on, the so-called "Turone's goal" remained a hot topic in Italian football for decades to come.
