Script:

Juan Manuel Marquez held a training session in Mexico City on Wednesday.

The 39-year-old Mexican is deep in training for his fourth fight against Filipino fighter Manny Pacquiao.

Marquez has had two losses and a draw in his fights with Pacquiao, but all three of those decisions were controversial.

Marquez, a four-division world champion, has put Pacquiao to the test more than any other opponent.

Having fought at 125, 130 and 144 pounds, their fourth fight will be a straight welterweight contest at 147 pounds.

Pacquiao comes into the bout following his first loss since 2005, a disputed decision to Timothy Bradley.

The fight takes place on December 8th in Las Vegas.
