With one week to go before Michael Bisping and Georges St-Pierre face off for the middleweight title at UFC 217 in New York, the trash talk is hitting full speed.

Bisping, who has never met a microphone he didn't like, has done much of the talking, and called out GSP once again during Thursday's UFC media lunch.

This time, his target was GSP's welterweight title run, which he doesn't think is as impressive as many others think it was.

St-Pierre held the welterweight title from 2008 to 2013, but Bisping told MMAFighting.com that it wasn't as impressive as it looks on paper, as he was fighting the same underweight people over and over:

“He’s fought a lot of the same people over that period,” Bisping said. “He’s fought them multiple times. And if you go through the opponents. I mean, BJ Penn, who he fought twice or three times, he’s a featherweight, right? Johny Hendricks, I mean look at Johny Hendricks these days. But still.

“Nick Diaz is a welterweight. Carlos Condit, oh, that’s a good win. Josh Koscheck, Dan Hardy, Thiago Alves — lightweight. BJ Penn — featherweight. Matt Serra — lightweight. These are all smaller guys.”

Meanwhile, Bisping is a true middleweight, so he's naturally bigger than GSP, which he believes will give him an advantage in next weekend's fight.

While Bisping admits that GSP will probably be stronger, he knows that he'll be tougher to move around than many of his opponent's past foes:

“He always had that strength and size advantage,” Bisping said. “Now, he’ll probably be stronger than me in this fight, I don’t doubt it. Because he lifts a lot of weights and he’s doing his amino acids every morning and this and that. He’s a real athlete. But I’m a bigger natural guy and he’s not gonna have that advantage.

"So yeah, he’s great and he’s beaten a lot of competition. But he’s had competition that has been suited toward him size-wise and skill-wise. This is a different matter. He can be as big as he wants. He’s still gonna be the smallest little sh-t that I’ve ever faced.”

The buildup to next Saturday's main event has been long and arduous, but it is finally going to happen, so all the talking will finally stop.

It'll be GSP's first fight in four years, so it'll be interesting to see how his bulk-up process has gone, while Bisping has been lying in wait for his opponent for months now.
