Look: Mayweather prepares for retirement bout with Berto, expects a pressure fight

The current welterweight and super welterweight champion aims to make it 49-0 next month and says Berto brings a lot to the table despite grumbles over his choice of opponent.

“Berto is a tough competitor. He’ll try to put pressure on me throughout the fight. A good jab can work well, but he’ll be throwing lots of combinations. My fast fight against Paquiao was more like a chess game. This time will be like Chinese checkers, a fast match. I have sparred a lot at the gym. I have like 10 sparring partners,” said Mayweather.
