Glover Teixeira says focus and alertness are the key to Alex Pereira earning yet another victory over Israel Adesanya when they meet at UFC 287 . Pereira (7-1 MMA, 4-0 UFC) has proven to have Adesanya’s (23-2 MMA, 12-2 UFC) number during their three combat sports encounters. The reigning UFC middleweight champ has won twice in kickboxing and once in MMA competition. The MMA win was the most high profile of the bunch, with Pereira pulling off a stunning come-from-behind rally that saw him claim the 185-pound belt with a fifth-round TKO of Adesanya last November at UFC 281. He’s now 3-0 in head-to-head matchups, but Adesanya has arguably won the overwhelming majority of the actual fight time
