American superstar turned in another boxing masterclass to beat Juan Manuel Marquez

Floyd Mayweather looked like he had never been away as he cruised to a convincing points win over Juan Manuel Marquez in Las Vegas - and then warned Manny Pacquiao he can get better.

More than 20 months after defeating Ricky Hatton in the same MGM Grand arena, the 32-year-old American dominated his Mexican opponent throughout a one-sided contest.

Mayweather had Marquez down with a crunching left hook in the second round, produced a cut above his right eye soon after and looked set for a late stoppage as he piled on the punches in the 10th and 11th rounds.

However, Mexican warrior Marquez, who had never been stopped in 55 previous fights, hung on bravely for the final bell and Mayweather had to settle for moving to 40-0 via the judges' emphatic scorecards.

"He is as tough as nails and I take my hat off to him," said Mayweather. "But I've been off nearly two years and I can get better."

'Money' Mayweather is now a 1/2 favourite with Ladbrokes to beat Pacquiao should they face each other next year, with the Philippines fighter 6/4 and a draw 25/1.

However, 'Pacman' must first get past the tough challenge of Miguel Angel Cotto in Nevada on November 14.

In what will be his first outing since crushing Hatton inside two rounds in May, Pacquiao is 1/2 at Sky Bet to win that contest, with Puerto Rican Cotto 9/5 at best with sportingbet to successfully defend his WBO welterweight title.

Mayweather was also quoted at 2/7 by Ladbrokes to beat Shane Mosley in 2010 after the pair exchanged words in the ring after his win over Marquez.

"Mayweather's speed and defence were as good as ever and will provide huge problems for any future opponent, whether it's Pacquiao, Mosley or anyone else," said Ladbrokes spokesman Nick Weinberg
