The former Netherlands striker says the Real Madrid man needs to improve his output when he is isolated up top and called for him to model his game on Brazil legend Ronaldo
The Frenchman scored 32 goals in 52 appearances last season as Real Madrid went on to claim the Liga title but cut a frustrated figure for Les Bleus as they slumped out of Euro 2012 in the quarter-finals.
And Kluivert, who netted 40 times as he amassed 79 caps for the Oranje, has called for the former Lyon star to modify his game in order to help his national team.
"Benzema is really strong but he should focus more on his job as a forward and, as the English say, be the target man," the 35-year-old told France Football.
"He knows how to perform, we see it every week for Real Madrid. But it is also true that he plays there with partners who help him and are closer to him in the box.
"When the players around him are attacking, he becomes strong. But he isn't as strong when he is more isolated. He must model himself on Ronaldo, I think."
The former Barcelona star went on to question France coach Laurent Blanc's negative approach during his side's exit from this summer's tournament at the hands of world champions Spain.
"Laurent Blanc has chosen to oppose the offensive qualities of Jordi Alba rather than force him to defend. In my view that was a great mistake," he added.
"Each [coach] works in their own way and, for some, it seems normal not to explain. But, for others, it is questionable."
The retired striker also commented on two of the tournament's outstanding teams in the shape of Germany and Spain, hailing their respective qualities.
"There are similarities between Germany and our teams [Netherlands in 1998 and 2000], in the ability to combine speed and patience in the game," he continued. "But what I find even better is that they do that with young people.
"Spain have a lot of quality also. But I find that it is not really the system which is the most dangerous, but more the quality of the players and their combinations."
