Cristiano Ronaldo reportedly swore multiple times as he left the field during Real Madrid's 2-2 draw at Las Palmas on Saturday.
The 31-year-old looked visibly frustrated to be substituted off by manager Zinedine Zidane in the 72nd minute of the contest, shaking the Frenchman's hand but then appearing to mouth something in the direction of Madrid representative Garcia Coll.
According to AS citing lip-reading experts working for the Cuatro TV channel, Ronaldo said: "Why me? I do everything to make it 2-1... for fuck's sake!"
The striker then said the word "fuck" in Portuguese, as well as a "mother-fucker" in Spanish, before ending his rant with: "There's 20 minutes left, 20 minutes!"
Zidane has since insisted that Ronaldo was taken off in order to preserve him for Tuesday's Champions League encounter with Borussia Dortmund.
