It's hard to explain.
The defenders I mentioned had an x-factor.
Everyone will agree that Benzema is a great and even a legendary CF right? But I say he is no super star, but Lewa is, Sheva was, Drogba was etc.
It's hard to explain, you just know it.
I get your point.
But were Nesta and Maldini more charismatic than Lahm? I remember Maldini as a relatively calm guy on the pitch, same with Nesta. Their leadership and ability to read the game was outstanding. Lahm was leading more by example and never recieved a red card in his career, Nesta and Maldini were very intelligent defenders too.
Benzema not being viewed as a superstar might be because he was always overshadowed by Ronaldo and to some extent Bale in the first 3-4 years.
Now that he's the sole striker in front we really start to see his qualities as a goalscorer. If he had the role of a Lewa, Sheva or Drogba from day 1 as the number 1 man in front I think we would view him differently.
Not to forget he scored 72 goals in the CL, he's the 4th highest goalscorer in the history of the competition. He's nly behind the two aliens Ronaldo and Messi and a historic great striker like Lewandowski.
