Floyd Mayweather Jr. (42-0, 26KOs) is hoping that Pedro Diaz, the Cuban trainer of WBA junior middleweight champion Miguel Cotto (37-2, 30KOs), is not filling his boxer's head with the idea of expecting an easy fight on Saturday night at the MGM Grand in Las Vegas.

During a few recent interviews, Diaz discussed how he examined the last ten fights of Mayweather and he "wasn't impressed" with the undefeated fighter's skill set.

"I'm not Antonio Margarito, I'm not Yuri Foreman. He's facing Floyd Mayweather. This is a little different. I don't want them to remotely put in his mind that this is going to be an easy task. I don't think he thinks this is going to be an easy task," Mayweather said.

Mayweather plans to start fast in the fight, noting  - "even though Antonio Margarito cheated, he's not that fast and he was still able to hit [Cotto] with those shots."

He also feels Cotto can be mentally tricked inside and outside the ring.

"You let yourself get talked into going down to 145 [against Manny Pacquiao] when you could have said 'absolutely not' and you still could have got the fight. Then you had the fight [against Margarito] with loaded gloves and you stayed with the promoter [Top Rank] and they talked you into getting in there [with Margarito] again," Mayweather said.
