"We are here. Have their people call his people - which is me. We can have a conversation."
McGregor's ability to settle in the WWE would come into question. He has previously commented that he would "slap the head off the entire [WWE] roster", which could hinder his integration into the locker room.
But on-screen WWE manager Paul Heyman, the promoter of 1990s wrestling organisation ECW, believes McGregor's ability to earn money would overshadow any concerns.
In a recent interview with Yahoo, Heyman said: "Who cares if the locker room would embrace Conor McGregor?"
"If Conor McGregor can be a revenue driver for WWE, if he can sell thousands and tens of thousands of tickets, if he can move millions of T-shirts, who cares if anybody in the locker room likes it or doesn't like it?
"They just have to learn how to accept it or draw more money than Conor McGregor so they have the leverage to say, 'I don't want that guy in my locker room'.
"Until they can drive the revenue a Conor McGregor drives, then perhaps they should get used to the fact that people like that will always get offers to come in and, as the old saying goes, draw money."
McGregor performed a strut inspired by WWE majority owner Vince McMahon's famous power walk during his victory against Alvarez.
