What's laughable is how you describe Varane. The way you compared him to Smalling made it seem as if you considered the latter superior.
Smalling isn't potential world class, Varane is. That's the difference. Varane will likely go on to be the best CB in the world in a few years, how one earth can you describe him as a "pussy cat"? You must be one of the very few people who don't rate him.
He's exceptionally fast, a brilliant defender and very good in the air. He's not the strongest but that's not his style of defending. No idea how you think Smalling is more commanding in the air, even though he's 6ft3 Varane jumps like a kangaroo, whereas I've seen Smalling constantly bullied despite his height. He's really quite poor for such a tall guy. It makes me think you don't watch him at all, as that's one of his biggest strengths, how brilliant he is aerially. He's easily beaten the likes of Pique on a consistent basis in this field.
How is that cringey? Smalling craps himself every time he receives the ball, Varane doesn't. That's what I mean. He's good on the ball and can play a bit, Smalling is incredibly limited, one of the worst in the league in terms of how he is on the ball. For a top side that's not good enough.
