A potential opponent put out a not-exactly-welcome advice for former UFC middleweight champ Anderson Silva, as "The Spider" is once again training for the Octagon after a bad left leg fracture. 

Nick Diaz, his potential comeback opponent, told Fight Hub TV about one drastic change the top pound-for-pound fighter should impose and he seems serious. "I don't talk no s**t. I aint trying to talk no s**t," he said. Watch the video here.

"I'll tell you what, I think he should fire his trainer and hire himself a boxing trainer that teaches him how to put punches out," the 30-year-old welterweight from Stockton, California, said, as reported on MMA Fighting.

Saying Silva is one fighter he wanted to face for a long time, he added: "Of course he's got as many fights as he wants to have, but people saying s**t like, 'He should retire. He's not going to be the same.' I'm like, 'Fire your coach and get somebody to train your punches.'"

Diaz also recently remarked that Silva had a big enough name to lure him back into action after a failed attempt to challenge Georges St-Pierre at UFC 58 last March. He also said the matchup would be "potentially one of the biggest fights in MMA history."

"His last fight, he had punches for [Chris Weidman], but he didn't have no punches," Diaz told Fight Hub TV. "Know what I'm sayin'? That was the key, putting punches out there; but [Silva] had no punches for that guy. So then he started lobbing kicks out there and you saw what happened to his leg. He didn't have no answer for it."

Diaz was referring to the UFC 168 in December, a rematch the 39-year-old Silva lost due to a leg fracture he sustained while fighting middleweight champion Weidman. Both men are on two-fight losing skids, MMA Fighting said, and would come from the sidelines if and when they face off.

However, the Silva-Diaz fight is not concrete yet, Diaz said in this recent interview with Fan TV. But the match which Silva will book will coincide with his much-awaited comeback early next year.

Diaz has been notorious for stirring up conflict among other fighters as a strategy to get desired matchups, KDrama Stars said. He did the same thing to get the former welterweight champion Georges St-Pierre against him, the report noted. 

His comments against Silva and his team could be to that end, especially knowing that Silva considers his team "family." In recent reports, he was quoted as saying: "Here at Team Nogueira, we are family. Ready and determined to do that, we have to do."
