Sarah Kaufman wants the chance to become 2-0 against fellow former Strikeforce champion Miesha Tate, as she continues to call her out for a fight in the UFC.

Kaufman took to Twitter recently to ask Tate when she’ll be ready. Back in 2009, Kaufman (17-2) scored a decision victory over Tate to improve to 9-0 at that time.

Kaufman recently picked up her first Octagon victory when she scored a decision over Leslie Smith at The Ultimate Fighter Nations Finale. Her initial UFC fight was declared a no-contest after Jessica Eye failed the post-fight drug test.

The Canadian is a former Strikeforce champion, having lost the belt to Marloes Coenen in 2010. She was unable to regain the title when she met Ronda Rousey in 2012.

Tate (14-5) is also coming off her first win with the promotion, as she bested former No. 1 contender Liz Carmouche at UFC on FOX 11. Tate was unsuccessful in her two 2013 UFC fights, falling to current UFC champion Rousey and Cat Zingano – both in the third round via finish.

On Twitter, Kaufman was asked about a potential fight with Invicta FC’s Lauren Murphy, who is 8-0 0 and the title holder in that promotion.

“She isn’t signed to the UFC fight now,” Kaufman wrote. Murphy responded to the post, asking about a possible move to the UFC, which Kaufman said would probably be tough because “I would think you are in a championship clause as no organization wants to lose their champ!”
