Carl Froch admitted he was on the edge of his seat but believes Floyd Mayweather "outclassed" Conor McGregor in their light-middleweight fight in Las Vegas.
Mayweather took his record to 50-0 by stopping Irishman McGregor, who was making his professional boxing debut at the T-Mobile Arena, in the 10th round.
Four-time world super-middleweight champion Froch praised the UFC star's resilience but the 40-year-old was not surprised by the result.
Froch, speaking on Sky Sports Box Office, said: "He (McGregor) did well from the fact that he's a mixed martial artist. If that was a boxer, you'd say it was an outclassed job, a mismatch.
"In reality, he (Mayweather) was in there with a UFC fighter. Conor came, he was proud, he tried, he didn't go over.
"It was a great event, promotion, a good show, we've all been on the edge of our seats. But what happened is what we thought would happen."
The 40-year-old Mayweather, fighting for the first time in 714 days, announced after the fight that he will never fight again, ending his 21-year career in style by controlling an all-action fight that thrilled the 14,623 fans in attendance and watching around the world. With Mayweather coming forward just like he promised, referee Robert Byrd stopped the super welterweight fight at 1:05 of the 10th round as Mayweather punished McGregor with a series of blows that staggered his weary opponent.
With the win, the five-division world champion from Las Vegas becomes the first boxer to finish his career at 50-0, eclipsing the record he had previously shared with the legendary Rocky Marciano.
All three judges - Dave Moretti (87-83), Burt Clements (89-82) and Guido Cavalleri (89-81) - had Mayweather ahead on the scorecards at the time of the stoppage. SHOWTIME's unofficial scorer Steve Farhood had Mayweather ahead by the score of 86-85.
