Poland's Blachowicz, 38, will defend his light heavyweight title for the second time this year against Brazil's Teixeira, 42, in the main event of UFC 267 in the United Arab Emirates.
But despite this, Blachowicz insists that there's 'no bad blood' between him and the Brazilian.
To him, Saturday night's fight with Teixeira is nothing personal, no matter what people say.
In fact, he would even go so far as to say they are 'friends'.
But that won't stop him from trying to remove Teixeira's head from his shoulders.
“He’s a great opponent with great skills,” Blachowicz said in a press conference.
“A lot of experience. He’s longer than me in this sport, so we are friends, no bad blood between us, but that doesn’t change anything.
"When we go inside the octagon, the fight will start, and I have to knock him out, and I will do it.”
Blachowicz is a 2/1 favourite in only his second title defence at 205 pounds and his first since he beat Israel Adesanya to defend his belt on March 6.
Blachowicz and Teixeira were to have met on September 25, but the bout was postponed and moved to October 30.
"I think experience, he knows how to use his experience. He has very good cardio, he knows how to use his boxing skills," he added.
"First of all he takes you down, makes you tired, then he finishes you on the ground or he knocks you out. But we are ready for that, we have trained for that.
“A lot of fighters make mistakes. When they hit him hard, they try to finish him too fast. He catch them in his game because he has a lot of experience, and he knows how to use it.
"I am ready for that. I will show how I’m going to defeat him on Saturday. When he makes you tired on the ground, he is dangerous everywhere, but we've trained everything for this fight."
He continued: "I've focused a lot on the ground game, I've got the best fighters on the ground in Europe, even in the world, so I'm ready for this part.
"I will not be afraid because if he takes me down I'm going to be ready for that.
"But of course I don't forget about stand-up, I have to keep my hands up.
"But anyway I think that he's going to use his boxing only to take me down and make me tired and then he's going to use his stand-up to try and get the finish."News Now - Sport News
