Even though seven years have passed since their first fight, Diego Sanchez still believes he holds a significant edge over Nick Diaz.
Sanchez, who recently decided to return to the lightweight division, could possibly stay at 170 pounds, if given the opportunity to fight Diaz.
He took to Twitter on Sunday in an all-out attack on the former Strikeforce welterweight champ.
"I whooped your ass [once], and I'll do it again....I'd rather whop your lil bro's ass after he loses 12/8 ain't scared at all," said Sanchez.
It's public knowledge that Sanchez and Diaz has never really seen eye to eye, but the posts seem to be fueled by Diaz's comments after the welterweight title bout at UFC 154 between Georges St-Pierre and Carlos Condit.
After St-Pierre defeated Condit in perhaps the toughest bout of his professional career, Diaz took to Twitter to share his thoughts:
The comments may have riled up Sanchez, who shares the same head coach as St-Pierre and Condit.
After the initial Twitter post, Sanchez began a snowstorm of trash talk aimed directly at Diaz:
YOU KNOW @nickdiaz209IS NOT GOING TO RESPOND DON'T BE SCARED BITCH— Diego Sanchez UFC (@DiegoSanchezUFC) November 18, 2012
YOU KNOW HE IS CALLING @ceasergracie WHAT DO I SAY WHAT DO I DO ? DIEGO IS TALKING SHIT..... PLEASE HELP MEDADDY— Diego Sanchez UFC (@DiegoSanchezUFC) November 18, 2012
A rematch with Sanchez makes sense for Diaz at this point.
Some have harked on the possibility of the UFC pairing Diaz with top welterweight contender Johny Hendricks. There is a great chance that bout could come to fruition, but it wouldn't be fair to make Hendricks climb another mountain in Diaz after already ousting three straight contenders.
Diaz is already coming off a loss to Condit, and after serving out his suspension, it will have been a year since he last competed.
Fans love a good old-fashioned grudge match, and there are very few fights lined up that will attract the same attention as Diaz vs. Sanchez II. As cliché as it sounds, styles make fights.
Could Sanchez be Diaz's kryptonite?
