Barcelona coach Xavi admits he was unhappy learning of the critical social media post aimed at Real Madrid star Vinicius Jr.
Barca board member Mikel Camps criticised Vini on social media for his showboating in Real's Champions League win at Braga.
Minutes later, after seeing the impact the post was having, the Bara manager deleted it.
However, the damage was already done and Camps' words made headlines just three days out from the El Clasico.
Xavi said: "If he deleted it, it is already important. We keep that, right? I don't like tension.
"I want a Clasico with respect and even mutual admiration."
On the game, Xavi also said: "We need to dominate the ball. A loss of ball, Madrid can destroy you. I always see it with difficulty. Madrid is strong, in good dynamics, difficult to predict anything.
"It's 50-50."
