Manny Pacquiao is apparently fighting fatigue as he gets stuck into training ahead of his WBA World Welterweight title match in November.
The Filipino's trainer Freddie Roach believes that Pacquiao's activities outside the ring may be affecting his performance inside it.
CBN News reported him saying: "We had a good week, overall it was a productive week.

"He's a little bit tired, he has two jobs, but we got through 10 rounds (of sparring). He looked good in the first six."
Pacquiao, who is arguably his countries greatest ever sportsman, also serves as a senator in the Philippines, a job that many politicians struggle to do by itself, let alone alongside boxing.
Despite his efforts away from the ring, Roach still believes his client can reach top form, even at 37-years-old.
He said: "He hasn't lost a step. He's still the same Manny Pacquiao I've always known and he's still a great fighter."
Pacquiao is finishing up his training in the Phillipino capital Manila and flies to Los Angles on October 22.
He fights Jessie Vargas for the welterweight belt on November 5, looking to take the title away from the American who has held it since March of this year.
At 27-years-old, Vargas will fancy himself to have speed and versatility on his side against the aging Pac-Man.
However, to rule the 37-year-old out before the bell even rings would be unimaginable, and Pacquiao will be fueled by the desire to return to the top of the weight class he used to dominate.
