Sean O'Malley's coach, Tim Welch, is giving Merab Dvalishvili high praise ahead of UFC 316.
O'Malley (18-2 MMA, 10-2 UFC) will look to avenge his bantamweight title loss to Dvalishvili at UFC 306 when the pair run things back in the June 7 headliner at Prudential Center in Newark, N.J.
Dvalishvili's (19-4 MMA, 12-2 UFC) resume includes wins over former UFC champions Jose Aldo, Petr Yan, Henry Cejudo, and O'Malley. His first title defense came in a win against formerly unbeaten Umar Nurmagomedov at UFC 311 in January.
Welch thinks there's no debate that Dvalishvili is the greatest bantamweight of all time.
