In 2008, Manso further enhanced his reputation as a play-maker while playing in the 2008 Copa Libertadores. He scored key goals and created important plays which helped LDU Quito win the tournament for the first time. LDU Quito therefore became the first and only team from Ecuador to ever win this prestigious trophy. Due to his skills, he was voted as part of the ideal Copa Libertadores team, along with fellow playmates, Enrique Vera, and Joffre Guerrón. At the 2008 FIFA Club World Cup, he again was vital to the team, helping LDU Quito advance to the final against Manchester United, which they lost. Manso was awarded the Bronze Ball for his performance in the tournament.
