I think the Cotto fight took a lot out of Malignaggi and he was hugely disappointing against Hatton.

It will be interesting to see how Diaz looks at the bigger weight, he's always had a fleshy physique and he'll have to firm up with the added pounds.

I think he'll bring the heat to Malignaggi and wear him down over the final third for a clear points win or maybe a late retirement.

IT'S telling that the most impressive performance I have seen from New Yorker Paulie Malignaggi was a losing one. I think when big-mouth Paulie stood up to Miguel Cotto for 12 rounds, having been busted up and punished severely, he added a whole new set of fans, who respected Paulie's toughness. No-one could ever again accuse Malignaggi of not having the stones to go with his mouth.

Three years and four wins from five fights later, that remains Paulie's greatest night. He put up far less of a fight against a faded (in hindsight) Ricky Hatton than a peak Cotto and even in winning and defending the IBF title he failed to impress.

Contrastingly, Juan Diaz brings his A-game to every fight. The Houston man comes in against Malignaggi having lost two of his last three but in good company and is still only 25.

Diaz's hustling high-energy style is perfect for off-setting Malignaggi's speed, good footwork and long-range pot-shotting. I feel he has more left at this stage of his career than Paulie and he is fighting at home.

The big question is whether Diaz can become the first man to genuinely stop Malignaggi. Paulie is a proud man and while Diaz breaks opponents down with a relentless attack to body and head, the smart pick has to be Diaz on points.

Diaz has lost two of his last and three and is moving up in weight, yet still figures to win this one. Malignaggi is fast but lacks the power to keep off a hard-working type such as Diaz, who should win on points.
