Tyron Woodley Says 'I'm the Greatest Welterweight' Ever, Sorry Georges St-Pierre

Tyron Woodley says his skull-crushing victory over Darren Till at UFC 228 solidifies him as the greatest welterweight fighter of ALL TIME ... putting him over Georges St-Pierre.

"The Chosen One" was fired up Monday morning after notching his 4th title defense in a row -- but admitted to TMZ Sports his elbow and hands were sore from bashing in Till's face.

"I don't think [he landed one shot on me]. I think the stats show one, but I didn't feel one. His head connected with my elbow a lot. That motherf**ker is sore," Tyron said.

"I'm like, 'Damn! What's your head made out of?!'"

As far as his legacy is concerned, Tyron says there's no question -- "I am the greatest welterweight of all time. No disrespect to Georges St-Pierre, but I don't have to fight him to prove that."

Tyron goes on to explain why he deserves the #1 spot over GSP.

By the way, Tyron has previously called out GSP to his face on "The Hollywood Beatdown" back in November ... but St-Pierre wouldn't commit to a scrap.

By the way, we also asked Tyron if there's a chance he'd fight Conor McGregor down the line -- since the two had beef backstage at UFC 205 back in 2016 ... and Tyron's definitely down.

Tyron told us Conor needs to focus on getting through Khabib Nurmagomedov next month first -- and then "maybe" the two can work something out.
