Clearly it is impossible for me to be sure of that, I just remember Busquets as not being slow and Rodri is pretty slow which is why he barely leaves his own half unlike, say, Fernandinho. I don't exactly feel the need to set up a sprint between them on FIFA to prove the point though as it doesn't matter. Rodri is a very solid, functional DM, nothing wrong with him. He's not particularly fast, aggressive or skilful though and does not compare to top DMs of the past in my view. More or less the same way I feel about Rice really, albeit they have slightly different qualities to each other.
