Liga de Fútbol Profesional, the governing body of Spanish top division, claims that during the 2010–11 La Liga season Cristiano Ronaldo scored a total of 40 goals,[1] while Marca newspaper, which is responsible for the Pichichi trophy, claims that he in fact scored a total of 41 goals.[2] The inconsistency of the data started during a match between Real Sociedad and Real Madrid, played on 18 September 2010, after Ronaldo took a free kick with a powerful shot towards the goal when in mid-air the ball was deflected on Pepe's back, beating the goalkeeper.[1] The view of Liga de Fútbol Profesional is backed by the Royal Spanish Football Federation and UEFA.[3] In addition, the 40 goals mark is also backed by his own club.[4] In 2011, Ronaldo received a European Golden Shoe award for his “40 strikes in La Liga” season and established the award's new point record at 80.[3][4]

I would give it as an own-goal too actually, but whatever LFP decide should count in the end. So Messi at 84, then. Or if they revise, 83.
