One-time UFC title challenger Teixeira will throw down with the UFC light heavyweight champion at the Etihad Arena in Abu Dhabi on Saturday.
Despite boasting a considerable amount of experience, Teixeira, 42, goes into his second title fight as a huge underdog.
At 42 years of age, it's fair to say that he may never get another chance to fight for the title again.
But it seems like the old warhorse still has plenty of life left in him yet.
Speaking at the press conference to the media, the 42-year-old said: "I'm feeling great ready to go."
When asked what keeps him going, Teixeira replied: "Passion, passion for this sport.
"At the end of the day you know lately there's more discipline about it, more like focusing on what I have to do to become a champion.
"Of course, it didn't work [out] before, so I was doing something wrong.
"When I fought [Alex] Gustafsson, when I fought Anthony Johnson, I was knocking on the door, like fighting an eliminator for the belt, and I couldn't get that title shot again and I say man, I'm losing time over here, what do I have to do?
"Looking for knowledge, you know, the PI and my coaches and my discipline, and asking myself like, how much do I want this?"
But Teixeira - who is good friends with Blachowicz - is expecting to get his hand raised on the night.
He said: "It's a hard thing to do and I'm glad that I'm here and I'm going to get it Saturday night.
"It's going to be a great fight because the style match-up is amazing. Jan, he likes to come in and finish fights.
"He goes after people. You know me, the record speaks for itself. I have the most submissions in UFC.
"Somebody's going to get hurt, and it's going to be Jan.
"I want to be champion, I'm going to be champion. That's the mindset I have right now."News Now - Sport News
