He also told Ariel Helwani who he would like to see McGregor fight next on Monday's edition of The MMA Hour
John Kavanagh described Conor McGregor's UFC 205 main event bout against Eddie Alvarez at Madison Square Garden as a "mismatch".
Speaking on Monday's edition of The MMA Hour with Ariel Helwani, Kavanagh said that what Alvarez brought to the table was not enough to trouble the now-lightweight and featherweight champion.
"He seems like a great guy," Kavanagh said. "Solid fighter. But if we're just looking at skill sets, I felt going in ... that this was a massive mismatch. That's nothing to say about him as a person. Just skills wise. I really felt like this would look worse than the [Marcus] Brimage fight. But that style of fight.
"I just felt you have to bring a hell of a lot more than that to the plate to trouble who I think is the best fighter on the planet right now."
McGregor defeated Alvarez via second round TKO to become the first fighter in UFC history to hold belts in two weight divisions concurrently.
"Skillset wise, I just thought it was a massive mismatch and I will humbly offer the evidence of the fight as [something that] warranted that."
The SBG coach also confirmed that Nate Diaz would be in his opinion the next fight for Conor McGregor to take at 155lbs.
The pair have met twice already this year at 170lbs and Kavanagh says that the Stockton southpaw would be the most capable fighter at lightweight, ahead of Khabib Nurmagomedov and Tony Ferguson.
