Gilbert Melendez is listening to Anthony Pettis.

It appears as if Pettis, the UFC lightweight champion, told Melendez the two should work on “selling” their upcoming planned title fight. While nothing has been set by the promotion, “El Nino” said December 6 in his latest Instagram post for a date.

The two will be coaches on the soon-to-air Ultimate Fighter season featuring an all-female strawweight cast. If they fight in December, it will be part of the Chris Weidman-Vitor Belfort UFC 181 card from Las Vegas.

Melendez is a former Strikeforce champion who lost via decision to Benson Henderson for the UFC title.

Pettis kept up his end of the trash-talking through social media, replying to Melendez that “u won’t make it out the 1st round!!! Your not even the number 1 contender Henderson is.”
