While many believe Chad Mendes has gotten better since his first meeting with Jose Aldo, the reigning UFC featherweight champion isn’t so sure.

Aldo will find out tonight if it’s true or not when he steps inside the Octagon at UFC 179 to put his belt on the line vs. Mendes.

Mendes has scored five straight wins, including four via knockout, to work his way back into the No. 1 contender role. But for the Brazilian, who is regarded as one of the top fighters in the world, he hasn’t exactly impressed him.

“Everyone’s always looking to evolve, but I haven’t been able to see it,” said Aldo, during a recent appearance on MMAjunkie.com Radio. “We haven’t seen him face a striker, so I haven’t been able to see where he got better. I do think his confidence has gotten a lot better; he’s gotten four wins, but the evolution part and getting better, I haven’t been able to see it.”

Aldo scored a first round finish of Mendes when the two first met in 2012, and he’s followed up with wins over Frankie Edgar, Chan Sung Jung and Ricardo Lamas since. While the desire to earn another stoppage win is always there, it isn’t something the champion will go in looking for.

“If I see the opportunity to finish the fight again, I will,” he said. “It doesn’t matter that I’ve knocked him out before. That’s my mindset. But if not, I can fight five rounds; it’s not a problem.”
