It was stated. Just indirectly.
He said"thanks to rikudo chakra my eyes aren't the only thing stronger"
We all know rikudo chakra effects eyes (yin) and body (yang)
Unlike noodles and sauce who only got 50% of Hagoromos rikudo chakra, Kakashi got 100% of obito's rikudo chakra. Thus he gets and increase to both instead of half.
you mean this page am i right ?

in this scan translated by *********** (in my opinion the more trustful translation) Kakashi only talks about the eyes, nothing else.
maybe do you know the viz scan ?
im not saying that kakashi is faster than kaguya nor that he could keep up with her in taijutsu.
i just wanted to show that kakashis foot speed (shun shin) should be not underestimated, especially not when kakashi had a small advantage (in this situation kakashi was faster near kaguya because she flew in his direction with high speed too, there were about to clash each other)
Kaguya also was surprised of kamui, which put her also in a disadvantage, but the speed of kakashi was his own just in the right timing.
The Mangekyou sharingans powered with the rikudos chakra, allowed kakashi to see through kaguyas speed and surprising her with kamui, which gave him an opening to strike her with his own speed.
Current kakashi would easily gets blitzed by kaguya now that he lacks the sharingan, no disuccion !
What do you think about this ?
