Yeah, the thing is Busquets and Alonso were different players too, just because they played midfield and were the best in their position. Busquets and Rodri are more similar than Alonso and Busquets.
In a way, isn't Kobbie more like Busquets than Alonso? In that he can receive the ball in almost any position and get out the press. Kobbie is our most press resistant player we have.
On your last sentence, that is exactly what I thought Amorim plays, because Busquets or Rodri are not the most mobile of players, whereas Amorim wants real running power, which is why Ugarte did so well for him in the high press rather than a DM.
