Fulham came from a goal down to pick up an important win over fellow strugglers Palace, moving up to 14th in the Premier League table in the process.
The match was notable for two stunning strikes, and Jol believes that his side's first goal, scored by Pajtim Kasami, was better than Marco van Basten's famous volley for the Netherlands in the 1988 European Championships.
"It was unbelievably important to get a result. It was a game of importance for Palace too but we needed the three points," BBC Sport quotes Jol as saying.
"The goal we conceded was sickening but we showed some response and a fantastic Pajtim Kasami goal with his wrong foot. I haven't seen him do that before. It was better than people think because he had to control the ball on his chest and then put it in the other corner, it was a really good goal from a talented boy.
"Marco van Basten's goal was totally different and you can't compare the two but this one was better. He had to sprint 30 yards, take a touch and then score, it is one of the goals of the season."
Fulham have now won two matches in a row and will face Southampton in their next game on Saturday.
