I believe if he's at 90/95% before the Tour, like he was before the Vuelta 2023, Visma will decide to put Vingegaard in the Tour, because he can still fight for the victory and improve the shape until the last week, where everything will be decided.
Now, this can be "wishfull thinking" by my side, but i believe he will be in the Tour, because Visma did not descarded yet his appearance there, and i believe a lot in his ability to recover faster. This guys doesn't appear to be humans. It's unbeliavable how fast Van aert is recovering after what happened to him.
