This will impact the latest transfer news as a Bernabeu great criticises long-running Arsenal target currently wowing crowds at the World Cup with France.
The 55-year-old, who represented Real Madrid for a seven year period, believes Benzema - currently on World Cup duty with France - needs to "toughen up and become more aggressive" if he is to cut it at the Estadio Santiago Bernabeu.
A five-time La Liga winner and UEFA Cup titlist with Real, Sanchez fired his way into Madrid fame as he is sixth in the list of all-time goal-scorers having netted 208 goals from 282 outings - a ratio of 0.74 goals per match.
Renowned for his acrobatic style, Sanchez had pace, poise, aerial prowess and long-range bullet-shots. He also converted numerous bicycle kicks (Huguinas) which were duly celebrated by somersaulting tirelessly in front of an adoring audiance.
Sanchez gave that little bit more - he entertained. And that is perhaps what he is imploring Benzema to do in order for the Frenchman to emulate himself, Raul and Alfredo di Stefano.
"Benzema is a player who can be a number 9 or a number 10, but he needs to be a bit tougher, a bit more aggressive, to show a bit more character," he is quoted by MARCA to have said.
"It will be hard for him to change now, and I do respect his style. But to be at Real Madrid you need that little bit more."
Benzema has long been on Arsene Wenger's shortlist of targets and there were rumours of a £30 million bid being placed last summer and then again in the winter transfer window, however, a recent statement from the player's agent indicates that the striker - who scored twice in a man of the match performance against Honduras recently - wishes to remain in Spain.
