Many consider former UFC heavyweight champion Frank Mir to be the best in the division when it comes to jiu-jitsu.

Mir, however, tips his cap in the direction of another fighter when making that statement: Fabricio Werdum.

Werdum will face a foe familiar to Mir in his next fight, as the Brazilian is set to meet Antonio Rodrigo Nogueira. The two will first coach on the second season of The Ultimate Fighter from Brazil.

“People put me down as one of the best submission artists, but as far as jiu-jitsu artist, I think Werdum is probably the best jiu-jitsu artist in the heavyweight division,” said Mir, during a recent interview with Fight Hub TV.

As for the upcoming bout between Werdum and Nogueira, Mir believes his former adversary could be in trouble.

“I think it’s going to be a difficult fight for Nogueira,” said Mir, who owns two wins over “Big Nog.” “I don’t think there’s any shame in going out there and losing as long as he puts forth a good performance.”

As for Mir, he will return to action in April when he faces Daniel Cormier. He has not fought since a loss to then-UFC heavyweight champion Junior dos Santos in early 2012.
