The Real coach was forced to miss the game due to local rules over self-isolating.
Bettoni said, "Zidane was very delighted with the team's attitude and the way they played.
"I congratulated the players as he would have done. There's nothing special. Every game is a different story. I'm pleased to get the three points and for the team's performance.
"We're now going to rest and prepare for the match against Levante."
