Tyson believes Mayweather stands alone at the forefront of boxing: "He controlled the fight, he has great endurance, he did a really good job.
"It's his era, his time. He is in invincible mode now - no-one can stand with him at this particular moment."
Former world cruiserweight champion Johnny Nelson was surprised by the margin of Mayweather's victory. He said: "He shocked me and shocked everybody because he stepped up another three, four, five levels and shut him out. It was a complete masterclass.
"The whole thing of boxing is hit and not be hit. That's what he did."
Former world featherweight champion Barry McGuigan was not surprised by the manner of Mayweather's victory. "Mayweather was much too smart and quick for Manny. Just as I predicted - boringly one-sided," he tweeted.
