He says the Reds cult-hero feels compelled to stay at Anfield for another season because he is loved by the fans.
But Cavani said: "The fact is that Luis is one of the top strikers in the world and he wants to be playing Champions League football.
"Of course, Liverpool are not going to make it this season.
"But of they don't make it next season then they will have a problem.
"Luis would love to play in the Champions League with Liverpool.
"But if he can't then a player of his quality needs to play for a club where he can.
"I know it meant a lot when Liverpool stood by him through some tough times and he has a lot of love for the club and their fans."
