John Cena sat down with Michael Cole and discussed his ongoing feud with Seth Rollins, his mutual interest with Dean Ambrose and more.

Cena spoke about Night of Champions on Sept. 21 at the Bridgestone Arena in Nashville where he was close to defeating WWE World Heavyweight Champion Brock Lesnar when Rollins interfered to cause a disqualification.

"That was a difficult night," Cena said. "Not just because I was so close in what I thought was defeating Brock Lesnar, but because I was coming off of a pretty one-sided contest at SummerSlam and I really had something to prove not just to the WWE Universe, but to myself that night."

Cena also said that Lesnar appears to be unstoppable.

"I don't know who could stop Brock Lesnar," Cena said. "Right now Brock Lesnar is the WWE World Heavyweight Champion. He has defeated The Undertaker, every other Superstar in his path. I'll be the first to tell you he cleaned my clock at SummerSlam. So what did I do? I got right back on my horse. I said you know what? I'm gonna go at this guy and I'm really gonna try to take it to him. And I did, at Night of Champions, I took it to him."

Cena also talked about targeting Rollins now and said that Rollins was foolish to try to cash in his Money in the Bank briefcase on Lesnar at Night of Champions.

"I don't think Seth truly knows -- he's never seen anything like Brock Lesnar -- and he doesn't know what it's like to be in the ring with Brock Lesnar. And that's why this guy is now my target, because of his sheer stupidity."

Lastly, Cena touched on Ambrose also having his sights set on Rollins.

"I can't blame Dean for that," Cena said. "Seth Rollins tried to end the guy's career. This is what I do, this is what I love. If some guy tried to end my career, I would spend every waking minute trying to get him to pay that back so I understand."
