He didn't attack Kuss and Roglic. He attacked Ayuso, Mas, Vlasov etc. Kuss and Roglic had the opportunity to close the gap, just like Vingegaard did on stage 6 when Roglic was the first to attack. Roglic also tried to attack on Bejes but failed to drop mas and Ayuso.
Roglic, though, attacked Vingegaard and Kuss since they were 3 Jumbo Visma in front alone. No Mas, no Ayuso, no Landa. Do you understand the difference?
Also, Vingegaard won his stage on Tourmalet, and he won a stage for NVH.
Vingegaard isn't in the red jersey, he says he wants Kuss to win. The question is all about what Roglic will do today; will he show his true colors or accept GC Kuss?
