Former Barcelona star Xavi did not hold back in his assessment of Paris Saint-Germain's defeat at the Santiago Bernabeu, describing the 3-1 Champions League loss to Real Madrid as an "injustice".
European titleholders Madrid scored twice in the final seven minutes to take command of the last-16 tie after Wednesday's opening leg in the Spanish capital.
PSG broke the deadlock thanks to Adrien Rabiot in the 33rd-minute before Cristiano Ronaldo converted a penalty on the stroke of half-time.
The French visitors controlled proceedings in the second half but sensationally collapsed during the closing stages as Ronaldo and Marcelo condemned PSG to a two-goal defeat.
