This is an excellent step up fight for Natalizi who is starting to show promise as a pro. Teffahi has been a fringe European level operator for a while and has caused a few upsets.
Teffahi is now 38 and past his prime but should have enough tricks to go the distance versus the big punching Natalizi who is starting to put it together as a pro. I don’t think Teffahi will pull off the upset as Natalizi has a good combination of power and boxing ability combined with youth which Teffahi now lacks. I predict Natalizi looks good in winning a decision though may stop Teffahi late depending on how much hes declined.
