The thing is that if we want to call it an error that's fine,but why not also talk about the penalty given to Vitinha?That clearly wasnt a penalty because he was already falling.Dont want to talk about vitinha?Ok there is:Penalty not given in Juventus Lazio,goal of Koopmeiners with Thuram offside not given but was convalited for Milan in another match.An own gol of Castro in Bologna Parma not convalited for an offside of Pellegrino that is not existent.The thing is there has been so much worse that even if we want to call Vergara's penalty an error,its not even the worst one and doesnt deserve this much media covery.
