UFC featherweight title challenger Chad 'Money' Mendes has some strong words on one of his fellow 145lbers, according to sources.

It is of course, Irishman Conor McGregor. Since his knock out on UFC debut against Marcus Brimage he has constantly ran his mouth against the fighters in the featherweight division. He has talked about Mendes in the past saying he should be fighting at bantamweight.

This has sparked a response from the Californian native. Talking on the MMA Hour, Mendes said: "Bottom line, this guy is the biggest shit talker I have ever seen or heard in my entire life. Basically, what he's doing is trying to get up in the top mix as quickly as he can because he hasn't fought anybody. I don't know why this guy thinks he can win one or two fights against guys that are on a lower level and expect to be fighting for the title.

"So, he is running his mouth and talking shit to everybody and calling everyone out. That's all it is. I mean, this guy he needs to fight someone in the top five and I guarantee he will get his ass kicked. I don't see why he feels he needs to run his mouth, talking shit.

"It's one thing to build the fight up, but to make it personal and talking shit about people, it's not cool.

"This guy is just a shit talker who is trying to get to the top without doing the work. He needs to take his stupid-ass haircut, his goofy little suits and fight someone in the top five and prove himself before he doesn't any of that."

Mendez was then asked if he would fight McGregor. He said: "I would beat the shit out of Conor McGregor. It wouldn't even be a fight. I would knock that dude out in the first round. Guaranteed. The guy is a clown."

Mendes is not the only fighter who has responded to the Irishman. Champion Jose Aldo has spoke back about McGregor. Furthermore, lightweight Diego Sanchez is not happy with his comments and also wants a piece of the action.

McGregor is not the only person to try and talk his way into big fights. Chael Sonnen did so to meet both Anderson Silva and Vitor Belfort. Most famously, Jorge Rivera talked his way into a match up against Michael Bisping.

McGregor has a lot of ability however he is biting off more than he can chew for now. He must learn the skills to enter the Octagon with the elite featherweights gradually. He has a big task in beating UFC veteran Cole Miller who is on a two fight win streak.
