Adesanya (15-0-0; 4-0-0 UFC) has dazzled since making his debut in the UFC in February and became the first fighter to notch four wins in 2018, and a bout against the New Zealand-born Whittaker would draw a massive audience from New Zealand and Australian fans - especially if the title is on the line.
"If I'm being frank, Rob is lacking defensively and that's where I'll take him. And I can do that any way I want," Adesanya told the Daily Telegraph.
"I know he's a fighter who wants to go out there and bust people up, but I'm not a guy you mess with.
"And once I'm champion, there will be a lot more eyes on this division. I'm the guy making s*** happen."
However, Whittaker's attention was firmly on retaining his title in February when he fights American Kelvin Gastelum in Melbourne at UFC 234. Adesanya has already hinted he'll be staying ready as an option to step up if one of the fighters withdraws with injury, though it would not surprise if his title eliminator was fought on the same card.
Regardless of the outcome at UFC 234, Adesanya hinted one more win would give him the next shot against whoever held the belt.
