2) Israel Adesanya

The Last Stylebender might not have only fought twice in the year when others did more but the calibre of his opponents said it all.

He won the mind games against the dangerous Yoel Romero before destroying long-time rival Paulo Costa.

Many believe he is the best ever in the Middleweight division and Izzy now has plans to win the Light Heavyweight champion.

By the way, Adesanya is one of the few undefeated UFC stars and also is an excellent kick-boxer with a great record.
