Andre Berto CANNOT beat Mayweather — which is the point for Floyd and always has been

Barry McGuigan says 'Money' will never rank alongside greats such as Robinson, Hagler and Leonard for all his qualities because he's so reluctant to take risks

There is not a snowball's chance in Hell ofAndre Berto beating Floyd Mayweather in his supposed Las Vegas swansong.

Which is, of course, the point.

It has always been the point with Mayweather.

He is never going to do what Sugar Ray Robinson, Marvin Hagler and Sugar Ray Leonard did.

They took chances.

From an economic point of view, Mayweather is out on his own. He has played the game really well, and he is a fantastic talent. And technically, he is among the best we have seen — a genius, impossibly hard to hit.

But you come to the stage where you are thinking of your legacy, and the reality is he will not be considered the best because he is so risk-averse.

Mayweather has faced three unbeaten fighters in his career — Diego Corrales, Ricky Hatton and Saul Alvarez.

Corrales, FOURTEEN years ago, was the nearest of those to a risk.

But, six months before they fought, Corrales had announced he could not make 130 pounds again. What happened? He fried himself to make that weight because, even then, no-one turned down the chance to fight Mayweather, and earn the money that brought.

Hatton had already had 43 fights when he fought Mayweather and with his come-forward approach was tailor-made for the American.

Alvarez, a natural middleweight (160lb) was made to fight down at 152.

Mayweather beats those laconic Mexican fighters every day of the week — and twice on Sundays. He loves a slow pace because he is so fast. He just feints you out of your jock-strap, then flays you with counter-punches.

The most courage he has showed was in the first fight against Marcos Maidana, when he decided to trade and had to show a bit of pluck to prevail.

Mayweather does not lack courage, and on the odd occasions when he has been dragged into the trenches, he shows up.

All the greats have had their easy nights, of course they have, but according to Mayweather this is about sealing his place in history as the best of all time. And you don't do that against a modest operator boasting three defeats in his last six fights.

Berto has been selected to lose spectacularly, by knockout.

He is small and chunky with fast hands, but is crucially vulnerable around the whiskers. When hit by anybody decent he folds — as he will in the early hours of Sunday.

Hopefully, George Groves will spice the night on the undercard.

Groves is looking to make a statement against Badou Jack and bring that WBC super middleweight belt back across the Atlantic.

He has not impressed since that first fight with Carl Froch and we don't know how much that, and the rematch, took out of him. But I believe he will get the job done and continue Britain's great tradition in the division.
