Pandiani was reportedly left furious after Madrid star Ronaldo sarcastically asked the Uruguayan striker during the match how much he earned, a taunt which Pandiani allegedly responded to by instead naming the trophies he has won in Spain.
Pandiani had the last laugh as his side's victory on the night left Real's title hopes clinging by a thread but while he refused to recount what was said on the pitch, he has this week decided to put Ronaldo in his place.
"You have to be more humble," Pandiani told reporters. "When he wins the Super Cups, the King's Cups that I have in Spain, then maybe I will listen to him."
Pandiani said Ronaldo should act more like Barcelona star Lionel Messi - "the best in the world" - if he wants the respect of fellow professionals, while also suggesting the former Manchester United star's match-winning ability comes with the side-effect of over-confidence.
"As a footballer he is a phenomenon but to do the things he does, maybe he has a screw loose. With his gestures and his cocky way of acting, he is the one who creates all the problems every weekend."
Meanwhile, Real set up a Copa del Rey clasico final against Barcelona on Wednesday by beating Sevilla 2-0 at the Bernabeu to secure a 3-0 aggregate victory. Real coach Jose Mourinho said he was looking forward to a worthy decider, which will give his side the chance to avenge the stunning 5-0 thrashing handed out by the champions in the league this season.
"It is great to see two rivals meet in the final," Mourinho told Marca. "We had our difficulties, and this has hurt us throughout January. We paid the price, but have receovered enough to progress to the final. It has all been worth it because we are now in the Copa final.
"April 20 is a little strange for the final. We will now focus on the Copa later in the season. It was important for us not to lose control of this evening's match, and the goals gave us peace of mind. We have had a good competition, which tested us with a Madrid derby."
