Former player Tim Moyette expressed concern about some pretty noticeable flaws in Holger Rune's technique after watching him train in a social media clip.
The Danish player failed to live up to all of the hype that he had at the end of last year with many expecting him to start this year in a furious manner which didn't quite happen. He's still quite good but former player Moyette noted that there might be some things that are worrisome, especially his technique.
He saw a clip of Rune working in Miami under the watchful eye of Mouratoglou and responded:

"Call me crazy but he is working too hard here. Comparing it against video of Nadal doing similar drills, Rune looks much less fluid, less stable and not nearly as smooth."
He added another comment:
"I think there are many reasons to do this drill, but
whatever he is working on lacks flow and core stability. Novak's
stability and balance should be the goal. Players this young and
explosive need to work to limit variables and connect shot to shot
