Israel Adesanya vs. Alex Pereira is going down tonight at UFC 281 ... and not a damn person knows who's going to win.
But, there's one fighter who not only faced the men (others have), he beat them both (something no one else has done) ... Jason Wilnis, former Glory middleweight champion. Wilnis is 1-0 against Israel (decision win, 2017) ... and 2-1 against Alex (decision win in 2015, TKO win in 2012).
TMZ Sports talked to Wilnis ... and we asked him to compare the two world-class fighters.
