Lennox Lewis has praised the work for Floyd Mayweather Jr during his victory over Manny Pacquiao, calling the American a "great technician".
The 38-year-old was booed by some of the capacity crowd at the MGM Grand Garden Arena in Las Vegas after securing a unanimous points decision.
However, former undisputed world heavyweight champion Lewis took to Twitter to suggest that some boxing fans are overlooking Mayweather's technical skill and suggested that many spectators "want blood".
Mayweather, who added the WBA welterweight title to his WBC and WBO belts, extended his professional record to 48-0.
