When all these people support you , you want to be able to perform . 'He 's probably the most dangerous guy in the division in my opinion . I think he ’ s a great competitor . He ’ s got a solid , well-rounded game , he ’ s a great kickboxer , amazing jujitsu , I just feel like his biggest strength is his heart . He doesn ’ t quit , he just keeps coming.. 'His biggest weakness is that he ’ s never fought a guy like me . I feel like my angles and the things I throw in the Octagon are second to none . My prediction - knockout . I need a knockout , it ’ s been a long time since my last knockout and I ’ m not going past the first round . 'He 's a good fighter , but I 'm a great fighter . ' Dos Anjos has won his last three bouts , including a stunning first-round knockout of Henderson last August . And he has no fear about being the underdog once again . ' I am going to go in there and take my belt , ' he said . ' I do not know how the fight is going to go , but I know it will not go to the judges . I will not allow the judges to decide and it will not go five rounds . ' I will pressure him like I pressure all my fights . I will be ready for his style and he will not be ready for my power . I am going in there to take my belt . That is all I want from him . ' I am very excited to be the first lightweight champion from Brazil . The belt has a date to be mine and that will be Saturday . It 's in God 's hands . 'It does not bother me to be an underdog . I am an underdog in most of my fights . Maybe it is a good thing for me , he has all the pressure .

So , good luck to her . 'The UFC saw that I 'm ready and I can handle it [ the title shot ] . I was born for this . I 'm comfortable and I 'm treating it as any other fight . ' But Esparza plans to upset the Pole 's party with an early finish . ' I 'm hoping the fight is going to go how everyone thinks it 'll go ; grappler takes striker down and grappler wins . My goal is to do it in under 14 seconds , ' she said . ' I feel like I 'm most likely going to have the strength advantage ; I feel like with longer , lankier athletes they 're not as strong as athletes with my build . ' I only care about winning fights ; I don ’ t care about the hype or promotion behind it . If I 'm not the champ the hype and talk does n't matter . ' I think female MMA is the biggest female sport out there . We 're being put on the same stage as the men and sometimes headlining in Ronda [ Rousey ’ s ] case . We 're on top right now . '
