Aguero denied the accusations and fellow Argentinian Zabaleta wants to make sure all is forgotten by having a word with another of their countrymen before kick-off.
Zabaleta, 26, said: "I don't know what happened in the last game with Sergio in the tunnel.
"But I know some players from Villarreal, especially Gonzalo Rodriguez, and I will try to speak to him to say what happened in the last game is finished.
"We need to try to focus on the next game. That is most important for us and for the Villarreal players as well."
