Referring to his unblemished 42-0 record, Floyd Mayweather Jr. is quick to remind who ever will listen that “42 have taken the test, and 42 have failed.”

Mayweather returns to the ring Saturday night in Las Vegas to challenge light-middleweight champion, Miguel Cotto.

While Cotto will want to wake up Sunday morning with his championship belt, inflicting defeat on the brash Mayweather is the most coveted prize in boxing.

Former super-featherweight world champion, Alex Arthur, doesn’t think fighting at 154-pounds will affect Mayweather.

“It won’t bother him.  He did it against De La Hoya and coped fine.”  But added, “I’ve noticed him eating junk food in training and that won’t help any. He should be consuming more healthy high energy foods.”

An interesting topic of discussion leading up to this fight has been speculating which style Cotto may use against Mayweather.

Arthur said, “I think Cotto will try to box, believe it or not. But with a high tempo, Cuban style, put in place by (Pedro) Diaz his coach from Cuba.”

Although he has been pushed close on a couple of occasions earlier in his career, solving the Mayweather puzzle has been something none of his opponents have been able to do.

Arthur believes educated pressure behind a good single strong jab are the tactics which should be used to beat Mayweather, but he added. “No one can beat him at this present time, and I believe he’ll still be fighting in two or three years time.”

He continued, “Cotto is capable.  He has tremendous heart and skill set.  Does he believe he can win?  Yes, I believe he does.”

However, while Arthur is looking for forward to what he feels will be a fantastic fight for boxing, he doesn’t see Mayweather losing.

“I believe Floyd will win on points.  He just has too much in his armory for the brilliant Cotto.”
