Andre Berto has had five fights in the past five years and lost two of those.

And this is who Floyd Mayweather jnr expects us to get excited about as he chases Rocky Marciano’s mythical 49-0 mark?

Berto is so far down the radar of most boxing watchers that only hard core fans would have heard of him.

He’s beaten one fighter of consequence (Jan Zaveck) and lacks the star power of any number of opponents who would have been better, chiefly Amir Khan, Keith Thurman, Danny Garcia and Gennady Golovkin.

Khan chasing Mayweather so relentlessly these past two years has become an embarrassment, but it’s still hard not to feel some sympathy for the Englishman. He’s done far more to earn a crack at Mayweather and the riches such a fight would bring. Khan should move on and forget about the self-absorbed American showman.

Berto is a guaranteed win for Mayweather and poses little to zero threat against boxing’s king. Robert Guerrero even outboxed him a few years ago and we all remember how Mayweather bossed Guerrero.

Mayweather clearly hasn’t listened to his dad who suggested Floyd would be better off retiring than fighting easybeats.

Mayweather will probably get away with it because he’s talking about taking the action to (free) terrestrial television in September. It’s not because he’s a generous guy; it’s because Berto would be a bust at the pay-per-view office.

Doubtless much will be made of long-standing tension between Berto and Mayweather said to involve crank phone calls and other such nonsense.

In a brilliant twist, Argentina’s Cesar Cuenca edged closer to Marciano’s record by winning the IBF junior-lightweight belt last weekend, taking him to 48-0.

Mayweather wouldn’t recognise Cuenca if he walked in the front door, but it would no doubt grate his sense of justice to have another man tugging at his record pursuit.
