For me De Minaur is really right up there. It‘s also impressive, how he can maintain his kind of explosive acceleration and change of direction on the grass.
Medvedev and Alcaraz are also in the category of people who manage to get to balls, where you thought the point was over already. I think that‘s something which should be rated really high when it comes to movement.
I would actually put Zverev in there..maybe. I think he‘s also really fast and good in defense and can pull off some really tough shots at the end of his range.
