Yeah Gaara said he was they're, no Sharingan, or even Shino's bugs could detect Muu. He's moved more freely than anyone on the battlefield, between his invisibility, and double body jutsu shit. Additionally, that Dude never went 'all out' in a battle to the death match against anybody. He was like the Dude in the at tv commercial watching a fight scene throughout 3 tv sets in his house... he just got to join in the action occassionally before he got Ghost Whispered into the light.
Think it though Raichu has a 'chakra signal' his speed alone makes it impossible for a sharingan to keep up with. The sharingan ain't perfect, thats why Sasuke stayed held up inside of Imperfect Susanno, because sexy eyes or not, everything has its limitations.
