Xavi was unhappy with the VAR for cancelling a late Joao Felix goal.
The Portuguese had scored late in stoppage time, as Barcelona came from behind to level the scores.
However, Felix’s goal was ruled out, with VAR judging that Ferran Torres interfered with play from an offside position.
Xavi blamed the decision while speaking after the game.
Xavi said: “Félix’s goal ruled out? It seems that Ferran interferes in the play, but we don’t know with who. Who is he interfering with? It’s not clear to me.
“Just as he can cancel João Felix’ goal, he can also give it. I think Torres doesn’t interfere, whether Ferran jumps or not, the ball goes to the same place.”
