KUALA LUMPUR - Eight division world champion Manny Pacquiao has no problems or face any distractions in his training routine in Malaysia for the 'Fight of Champions', this Sunday [Saturday in the United States].

With only four days before the fight, the 39-year-old Filipino superstar said there weren't many differences in the conditions between the two countries.

"There is no difference between the Philippines and Malaysia...the weather is the same and there is just a small time difference. My training routine remains unchanged, as I go jogging in the morning and train at noon," he told reporters before a warm-up and training session at a hotel in Kuala Lumpur, today.

Pacquiao also known as 'Pacman', is up against the World Boxing Association (WBA) "regular" welterweight champion Lucas Matthysse from Argentina, in a much anticipated battle at the Axiata Arena Bukit Jalil.

Matthysse feels ready to go and predicts fireworks.

"Make sure you to watch the fight. It is going to be great. Two or three days before a fight, I focus on training and resting. The training is to make sure I’m on weight. I do enough to stay on weight because most of the work was done during camp. It’s about maintaining weight and fine tuning the plan. I’m resting a lot as well and getting great sleep. I’m at peace with my mind right now," Matthysse said.

"All we’ve been saying is we intend to return to Argentina with the title intact. It’s up to Manny if he wishes to retire after the fight."

Matthysse's trainer, Joel Diaz, says his boxer is in top form the contest.

“Lucas has been walking around 2 or 3 pounds over the weight limit. After dinner last night, he was only two pounds over. The weight has never been an issue. He’s been only a few pounds over for the past few weeks. We train for the fight, not the weight. Where we train [in Indio, Calif] it’s 116 degrees right now, so Malyasia is cold to us compared to that," Diaz said.

"A win over Pacquiao means a lot to me and the rest of our team because he train hard for it. I don’t think about how many times I’ve gone up against him as a trainer. We are facing a great fighter. A legendary fighter. Much respect to him. But when they get in the ring, it’s going to be a fight.”
