Among the many advantages Israel Adesanya believes he has over Paulo Costa is that the middleweight champion fights with calculation and precision, while his second-ranked opponent often reacts on emotion. MMA observers will see for themselves when the undefeated fighters meet on Saturday in the main event of UFC 253. Adesanya's second defense of his belt highlights the UFC 253 fight card from Fight Island in Abu Dhabi, with the main card set for 10 p. m. ET. Adesanya hasn't been shy about outlining the ways in which he believes he's the superior fighter and believes he will outclass Costa, who has stopped 11 of his 13 opponents. Adesanya is a -170 favorite (risk $170 to win $100), while Costa is a +150 underdog in the latest Adesanya vs. Costa odds from William Hill. In the co-main event, top-ranked Dominick Reyes (-260) faces Jan Blachowicz, who is getting +220 in the UFC 253 odds, for the vacant light heavyweight title.
