The goalposts have a long history of making great goals better. Notable examples include Sir Tony Yeboah's volley against Liverpool and the second best goal of 2014, James Rodriguez's hit against Uruguay.
In-goal camera was in it's infancy in 1993 but it really proved its worth in the top of the table clash from March of that year. Villa were a serious team then back-boned by a host of Jackie Charlton's boys. United were regarded as a mentally vulnerable bunch following their collapse the previous year. The result wasn't decisive in the eventual winner that year.
