Preview:

After dismantling Adrien Broner last December, Maidana earned himself the chance to challenge Mayweather at the summit of the welterweight division this year. The Argentine's ferocious start to their first bout five months ago momentarily rocked the five-weight world champion but his unerring speed and counter punching eventually saw him secure victory number 46.

But, despite the judges' scores of 116-112, 117-111 and 114-114 in Mayweather's favour, Maidana was credited with giving the Michigan-born fighter his sternest examination in years.

Five months on, Maidana is preparing for chance number two, becoming just the second man to earn a rematch with the champion. Considering Mayweather's recent claims that this is the first of his final three fights, Maidana has the opportunity to make history.

What They've Said:

Floyd Mayweather Jr

When I am in the ring I know what I have to do. Facing so many different styles throughout the years, making adjustments is second nature. [My legs] looked good in the first fight. When a guy like that is extremely dirty I have to take my time.

I am capable of changing. I'm faster this camp, a lot stronger, feel a lot better. We will have to see how the fight plays out. I am sure he is in good condition and we'll see what he brings.

I think I am faster because I am throwing more combinations this camp. The sparring partners have said I am a lot better. We have used some of the same guys and they say I am a lot stronger and faster this camp.

Marcos Maidana

Personally, I find it much easier to face up against Floyd this time. When we first fought, I thought I wasn't going to be able to see him, but I found him in the ring many times.

I don't agree with the statement I need a knockout to win. I think that I can win by decision or by knockout. The first fight was a very close fight.

It was a decision that was a majority decision, so I feel that I just have to make a few adjustments, put a little more pressure on, land better punches, and yes I can win, I can win by decision. Obviously the knockout would be nice, and that's a possibility as well."

Prediction:

Maidana's fierce start to their meeting in May was what won the Argentine widespread acclaim but, inevitably, Mayweather systematically wore his opponent down. Maidana has the rugged determination to force the issue in similar circumstances again but you feel the unbeaten American will be prepared to deal with an onslaught and once again box smart en route to victory number 47.
