Butaan overrating Varane, and some culers doing the same with Bartra. I'm a believer in Marc's ability, and I've defended him plenty in the past. He still shows a lot of room for improvement, primarily his tendency to use his arms to stop his man, (already highlighted by Bojan in the past). He can be out-muscled by players half his size. Varane on the other hand doesn't 've any glaring weakness, but he does make mistakes which can be attributed to inexperience.
As for the gif posted: Hummels won the header clean and fair. Varane should 've shown more presence, but there is nothing wrong (and I've said this several times) in being upstaged by a superior and more experienced player. Drogba has done the same to him. See no point is using it to bash a young talent. One could as well use a gif of Bartra being beat by Mussachio for the header, and he's only a year older. In short, both Varane and Bartra are not finished products. And even though the former has a higher ceiling, its possible Bartra can go on to 've a better footballing career.
