Freddie Roach, the trainer of Manny Pacquiao, is expecting Juan Manuel Marquez to use his bread and butter - by counter-punching - on Saturday night. The two fighters are going to meet for the fourth time at the MGM Grand in Las Vegas.

After three controversial decisions in the their prior meetings, both Marquez (54-6-1, 39KOs) and Pacquiao (54-4-2, 38KOs) have promised to close the show with a knockout.

Roach doesn't see Marquez going for a knockout, at least for too long. He predicts Marquez may attempt to fight with Pacquiao at close range, but he'll quickly revert to his old style of fighting once Pacquiao starts to tag him with hard punches.

"He says he's going to fight us this time. That he's going to stand there and he's going for a knockout. Marquez is a counter-puncher. I believe he'll run still. He might try to fight with Manny, but once he feels Manny's power he'll go the other way," Roach said.

"[Marquez] is a very good fighter, but Manny is a lot better for this fight than he was for the third fight. I don't think he really saw the best Manny yet. In the third fight [I thought] he would be the Manny who is using both hands. We had a few distractions before the fight and his mind wasn't there. I think he's going to see the best Manny and the best Manny will be way too much for him."

On the other hand, Roach expects Pacquiao to be very aggressive in the ring and sees him going for a knockout victory. Although Roach does admit that he'll be satisfied with a decision win.

"We've had four knockdowns in training camp. I don't think we've had knockdowns in training camp since the Cotto fight I believe," Roach said.
