Manny Pacquiao’s best days are certainly behind him. That much was abundantly clear during his WBO Welterweight title fight against Jeff Horn on Saturday. But he should’ve been good enough to walk away with the victory anyway. But he didn’t; Horn, who came into the fight the +450 underdog, claimed a controversial victory that set the boxing world alight.

Former Heavyweight Champ Lennox Lewis was among the first to speak out:

Wow! PAC loses by UD? One judge had it 117-111? 😳 Wasn't the fight that I saw! — Lennox Lewis (@LennoxLewis) July 2, 2017

This is what's wrong with boxing. Horn was very game but I'm hard pressed to see how he could have won that fight by any stretch! #PacHorn — Lennox Lewis (@LennoxLewis) July 2, 2017

And was joined by plenty of others:

You know what they say:if you want to beat Manny Pacquiao you have to beat him dirty. Mayweather did it, Horn did it #PacquiaoHorn #PacHorn — Jopay (@mariazippyy) July 2, 2017

Manny Pacquiao losing is why boxing is such a joke. How can people take this sport seriously anymore? Jeff Horn did not win that, sorry — Jason McIntyre (@jasonrmcintyre) July 2, 2017
