Manny Pacquiao's trainer Freddie Roach has admitted Juan Manuel Marquez deserves a fourth fight against the Filipino after the pair's latest bout ended in another disputed points decision. Pacquiao emerged victorious on Saturday night during their WBO welterweight clash in Las Vegas despite Marquez claiming he should have been crowned the winner. The contest went down to the Nevada judges' scorecards with Dave Moretti scoring it 115-113, Robert Hoyle 114-114 and Glenn Trowbridge 116-112.Roach had predicted the fight would be decided within six rounds but at the end of 12 rounds Marquez raised his arms, convinced he had done enough. He left the ring as soon as the verdict was revealed. "Everybody knows what happened. I think I won this fight again. I repeat, what do I need to do for the judges to give me the fight?" Marquez told reporters. Pacquiao insisted it was "very clear I won the fight" but said he would be willing to consider a fourth bout with Marquez: "Any time, any time. I am a fighter and my job is to fight in the ring."
